Welcome to the 12th Annual Engineering Design Day!

This is the best day of the academic year. This is the day when we when show the world how engineers help people and improve the quality of life by designing engineering solutions to societal problems. The Interdisciplinary Engineering Design Program at the University of Arizona allows teams of engineering students to work directly with industry and faculty on real-life projects. Students from across the College of Engineering work in multidisciplinary teams to solve design problems identified by industry partners, faculty, and student clubs.

This event only exists because of the hard work of students, mentors, faculty, and, importantly, the generous support of and partnership with many individuals and organizations. On behalf of our students and faculty, I would like to thank our sponsors for their support and the time spent by everyone mentoring and guiding our students.

This year we have 352 students majoring in various engineering disciplines demonstrating 64 completely original engineering projects, some of which will go on to be real commercial products. Please enjoy the day and ask design teams about their projects – our engineering students are enthusiastic about their designs and always welcome the opportunity to explain how they are going to change the world for the better.

Sincerely,

Jeffrey B. GoldbergDean, College of Engineering

Ventana Innovation in Engineering Award ($1,000)Innovation may include the novel use of existing components or the creation of entirely new components to meet customer requirements. The most innovative design will not only be a creative solution to a problem but also an effective solution that is well implemented. This award recognizes the team that has created or made use of components in the most innovative way, or demonstrated excellence in the implementation of innovative design in its project, or both.

AGM Container Controls Most Manufacturable Design ($750)While it is important to show feasibility of a product design through the build of a concept, it is just as important to design a product that is manufacturable and can be repeatedly assembled. Design for manufacturing, or DFM, is critical in a competitive market and history has shown that projects that fail to address lean design and DFM early in the design cycle often end up over budget and behind schedule. This award recognizes the team that has considered factors such as assembly, test, and ease of rework, which are indicative of a manufacturable design.

Criteria for judging include the completeness of the project analysis based on the above categories, thoroughness of the analyses, application of sound engineering principles and practice, a demonstrated understanding by team members of any tools or models used, reasonableness of all assumptions, and the quality of the documentation of the analyses.

Sargent Aerospace & Defense Voltaire Design Award ($750)The French philosopher Voltaire is credited with the saying “Le mieux est l’ennemi du bien,” which means “the best is the enemy of the good.” Similarly, Leonardo da Vinci is credited with the saying “Simplicity is the ultimate sophistication.” This award recognizes the design team that best emulates these ideals and resists the temptation to overly complicate the design to yield a clean, simple, elegant, lowest-cost design that simply works well.

Awards [continued]


13

Awards [continued]


Technical Documentation Consultants of Arizona Best Design Documentation Award ($750)Successful implementation of any innovative design requires that all members of the design and production team communicate effectively. Design intent must be communicated from the design activity to the rest of the team using design documentation with a clear map for others to reproduce the design based on documentation only. The mechanical portion of the design is evaluated on the use of drawings with geometric dimensioning and tolerancing, solids models, illustrations and presentations that can be used to manufacture and inspect design hardware. Software and other systems are evaluated on the use of documentation that clearly and fully describes the system.

Avilés Best Project That Exemplifies the Innate Art and Beauty of Engineering Award ($500) There is considerable math and science behind every engineering design, but what makes one design more desirable than another? Art and engineering are complex endeavors and it is not always apparent how they can and should work together. Many times the art and beauty of the design provide the competitive advantage and drive the success of the product. The combination of art and engineering creates the “wow” factor of the design. This award recognizes the team that has embraced and exemplified the art and beauty innate to engineering and science in creating its design.

14

Honeywell Team Leadership Award (Two Individuals at $250 each) This award recognizes students who best exemplify teamwork skills, including the ability to work cooperatively with others to produce high-quality work, to take the initiative, to support and respect the opinions of fellow team members, to give and receive feedback, to demonstrate effective leadership, to keep their team focused, and to elevate the work of their fellow team members. Nominees for this award are selected by their teammates.

Latitude Engineering Award for Best Physical Implementation of Analytically Driven Design ($500)Some engineering problems are straightforward: optimal solutions are found through the application of engineering best practices. Sometimes, however, the best design choices are not obvious, and only reveal themselves after a thorough analysis of the underlying physical principles. This award recognizes a design that could only have been arrived at after careful study and creative application of physics.

Prototron Circuits Best Printed Circuit Design Award ($500)This award recognizes the team that has designed or used the most elegant and efficient electronic circuits in its project.

Sustainable engineering is the process of designing systems such that they use energy and resources sustainably. Every engineering discipline is engaged in sustainable design, employing numerous initiatives such as design for the environment and design for recycling. This award recognizes the team that makes the most efficient use of resources in its project.

Universal Avionics Best Integration and Test Philosophy Award ($500)Many products consist of multiple subsystems that need to be integrated and tested as an end product. Designers have to consider the architecture philosophy early in the design, and consider ease of integration, interface protocols, grounding, harnessing, and so on. The test philosophy at the subsystem and system levels also needs to be architected early. This award recognizes the team that best embraces an integration and test philosophy in the design of its product.

University of Arizona Center on Aging: Bioengineering Solutions to Aging Issues ($500)This award recognizes the engineering team that best promotes the independence and quality of life of older adults through innovative yet practical bioengineering tools.

Mainstream-Disk Cavity Overlap Resistance FactorInterdisciplinary Engineering Design Program

Team 1301: Project SummaryThe goal of this project is to experimentally derive the optimal axial-radial overlap resistance factor within a rotor-disk cavity of a high-pressure turbine. Overlap resistance factors influence the amount of gas that is ingested into a rotor-stator cavity from the mainstream flow. In order to maintain safe operating temperatures in a disk cavity of an actual turbine, purge flow must be diverted from the compressor to cool the rotor disk. Choosing a favorable overlap resistance factor will reduce the amount of ingestion of hot gas into the cavity, and require less air from the compressor. This leads to a higher overall efficiency of the gas turbine engine. The project aims to achieve the goal by providing data on cavity ingestion flow rate versus axial-to-radial platform overlap ratios. The geometry of the designed test apparatus, along with the secondary/mainstream flows and rotational speed simulate the actual rotor-stator turbine disk cavity. Test variables include various radial gaps, axial gaps, purge flow rates, rotational speeds, and thermal conditions. The system measures temperature, pressure, and mass flow rate at critical locations to determine the configuration that maximizes cooling, by way of geometric resistance to ingestion flow, while minimizing the amount of purge flow.

Platform for Electrokinetic PCRInterdisciplinary Engineering Design Program

Team 1302: Project SummaryThe polymerase chain reaction (PCR) is an essential factor in the biological sciences and in medical diagnosis and treatment. PCR is an experimental process of amplifying DNA through repeated cycles of interval heating of a DNA and enzyme solution.The cycles include denaturation of the DNA helix, annealing of the primers, and elongation of the DNA sequence. The most common methods include quantitative PCR (qPCR) and step-down PCR in a thermocycler. The goal is to develop a prototype of an electrokinetic (EK) PCR device in accordance with the lab setup and experimental protocol of the Systematic Bioengineering Lab at the UA. The experiment facilitates EK-PCR, the amplification of a DNA sequence via the regulated delivery of cyclic voltage to the DNA chamber on a customized biochip. The current laboratory setup requires a lot of space because it includes several bulky pieces of hardware connected by extensive wiring. Furthermore, each device requires manual adjustment and constant monitoring throughout the entire protocol. The new platform consolidates and automates this process, while allowing for custom protocols. It includes a power circuit to supply voltage and effect a temperature change in the small DNA chamber on the biochip as well as a potentiostat circuit to measure the cyclic voltammetry at the site of the chamber.

Automated Guided Vehicle for Material DeliveryInterdisciplinary Engineering Design Program

Team 1303: Project SummaryAutomation has been an efficient way to reduce variation and lead time in manufacturing processes for many years. Automated guided vehicles (AGVs) have recently become a popular part of automation, with applications ranging from self-driving cars to automated material delivery within warehouses and manufacturing plants. The University of Arizona collaborated with Martinrea Automotive Structures, and Tecnológico de Monterrey, both located in Hermosillo, Mexico, to design, build and implement an AGV system for the delivery of materials across several cells on the production floor. Martinrea Automotive Structures is the division responsible for stamping, welding, and modular chassis assemblies. The goal was to develop an AGV system consisting of mechanical components that would satisfy the load requirements given; dollies that could transport stamped materials and sub-assembled parts to different production cells across the production floor while also being ergonomic for operator use; and an electrically controlled system that would serve as navigation for the autonomous vehicle at all times. Being an international and collaborative project, the UA senior design team visited the Matinrea Automotive Structures plant and the Tecnológico de Monterrey facilities to work with the engineering department of Martinrea and with engineering students from the Tecnológico de Monterrey in order to meet the project goal.

NASA Remote Imaging System Acquisition (RISA) ProjectInterdisciplinary Engineering Design Program

Team 1304: Project SummaryThe overall goal of this multiyear project is to research, develop, design, implement and test a handheld multipurpose imaging system for NASA. The system will be used on the exterior of space vehicles, in the crew cabin, and on planetary or lunar surfaces. The final design must function untethered for 12 hours, receive commands and transmit images wirelessly, and record still images using an autofocus feature or with user-specified focus. The camera must use a removable single liquid lens assembly and be able to record geometric measurements and images in multispectral regions. The system must also use components that have commercially available radiation-hardened equivalents and the case must protect the internal electronic components from electromagnetic interference and other hazards of the space environment. The specific goals of the 2014 RISA team included developing an optical test plan and testing the optical lens system and producing quantitative results for NASA. In addition, the team implemented an autofocus feature and developed a method to compress images sent to a remote computer. The team also established a groundwork for future teams by designing a camera case with extensive prototyping space.

High Energy Beam Laser Metrology DeviceInterdisciplinary Engineering Design Program

Team 1305: Project SummaryThis project encompasses the task of designing and building a portable infrared laser beam metrology device to measure beam propagation direction and location with respect to a mechanical datum. Systems to be measured are solid state laser output devices with an ideal direction of propagation. The system designed is to attach to the existing laser system employing a demountable kinematic coupling to a reference surface such as the output window bezel. The beam in question should not exceed 100 mm in diameter and 10 W in power in the infrared spectrum. The system should survive external forces typical for travel (up to 10 g). Significant design challenges are:

• Design of optics accommodating for wavelength in question.

• Selection of materials that will curtail energy absorption and thermal stress.

• Design of robust sensor housing.

• Measurement of propagation direction to microradian accuracy.

• Measurement of beam centroid location at exit window to 25 micron accuracy.

• Ability of system to withstand 10 g while travelling without subsidence.

Universal Hybrid Conversion KitInterdisciplinary Engineering Design Program

Team 1306: Project SummaryThe University of Arizona Electric Vehicle (UAEV) senior design team sponsored by the University of Arizona Electric Vehicle Club is motivated to improve gas and hybrid vehicles, and to design new super-efficient all-electric vehicles. There is an ever-growing need to provide simple solutions that promote a cleaner globe. People spend thousands of dollars on expensive hybrid cars looking for a way “to go green” and save money in the process. The goal of this project is to build a kit that promotes the same effects of global sustainability and personal economy. The UAEV senior design team is dedicated to building a universal hybrid conversion kit that regenerates lost potential energy. The kit must be able to fit any fuel-injected vehicle and increase city miles per gallon by harnessing power from untapped energy that would normally be lost to braking and idling. The design team was given only two requirements by the sponsor: collect a portion of lost potential energy, and build a start-stop system. Out of these two requirements sprouted many more subrequirements regarding maintenance, operation and performance specifications.

Camera System With On-Demand Polarimetric FilteringInterdisciplinary Engineering Design Program

Team 1307: Project SummaryThis project involves the designing, building, and testing of an optical system that uses a MoxTek pixelated polarizing filter (PPF) capable of alignment at an intermediate image plane to provide on-demand polarimetric filtering. Polarimetric filtering enables additional information to be extracted from a traditional imaging system and is commonly used in chemical engineering, manufacturing, and defense applications. Raytheon Missile Systems developed the concept and theory behind this project and required the design team to provide a platform for proof of concept and to advance the technological readiness index with only commercial off-the-shelf components. The system is capable of measuring the degree of polarization, as well as the polarization states, across a small field of view to an accuracy of 10 percent determined by a merit function known as the noise equivalent degree of linear polarization. Additionally, the project involved correlating theoretical performance metrics to actual experimental data and determining the sensitivities between PPF misalignment and system performance.

Saguaro Border Surveillance SystemInterdisciplinary Engineering Design Program

Team 1308: Project SummaryThe current US-Mexico border surveillance system has sensors that detect movement and send a signal to a central command station. A Border Patrol agent is then sent to investigate. This is potentially hazardous for field agents and a waste of time and money for Border Patrol. Motion detection does not determine whether the system has been tripped by an animal or by a group of armed and dangerous individuals. The goal of this project is to redesign this system so that it is safer and more practical, by designing and building a border surveillance system that is instrumented with a number of sensors that monitor and image the surrounding area to detect the presence of illegal border crossing. The requirement is that, upon detection, an image (or series of images) can be remotely displayed at a central command station. This image stream can also be directed to the field agents to view for efficiency and security. To ensure that the system remains intact and functional, the sensor and camera are housed in an artificial saguaro cactus for camouflage.

Specular Black Baffle DesignInterdisciplinary Engineering Design Program

Team 1309: Project SummaryMatte or gloss? In optical systems, unwanted stray light is usually trapped by diffuse (matte) surface coatings, but recent studies suggest that specular (glossy) surfaces can reduce stray light better than conventional diffuse surfaces. Baffles – tubes that block stray light from entering an optical system – have widespread practical use, ranging from consumer cameras to space telescopes. Despite the simplicity of the question posed, there is little experimental data to correlate reflection mechanisms with optical performance. Furthermore, the computer algorithms for simulating specular baffles have not been validated with real-world tests. The objective of this project is to design, model, and test the performance of a baffle. First, two different baffle geometries are designed: one using diffuse black paint, the other using specular black paint. Next, a simulation of both baffles is created with optical ray tracing software to predict the stray light performance. Last, the physical baffles are fabricated, tested, and subsequently analyzed, both in terms of specular versus diffuse performance and experimental versus theoretical performance. The ultimate aim of this group is to publish worthwhile data on the feasibility of specular baffles.

Lightweight Automatic Small Mammal RF Tracking SystemInterdisciplinary Engineering Design Program

Team 1311: Project SummaryIn the study of wildlife ecology, automatic tracking systems are important for statistical, remote sensing, and geographical information systems applications. Latin America’s tremendous diversity of wildlife and ecosystems creates many challenges for wildlife tracking. The goal of this project is to use radio frequency to track golden lion tamarins. Three receivers will be used to triangulate the position of tamarins over a time period of three months. Each tamarin will wear a lightweight collar that will transmit a particular frequency to distinguish itself from other transmitters within the region. Receivers will operate fully during the time that the tamarins are most active and will transition into a sleep mode otherwise, periodically tracking the monkeys’ locations. Additionally, receivers will use GPS in an effort to synchronize their clocks and reduce the possibility of error in locating the transmitter. Researchers will obtain stored information from each receiving unit in order to study the movement of the tamarins. The collected information will be transferred to a program that will collect the given data from all receivers and determine the location of each transmitter with respect to the range of the receivers.

Feasibility Study and Demonstration of a Head-Up DisplayInterdisciplinary Engineering Design Program

Team 1312: Project SummaryHead-up display (HUD) technology used in both commercial and military aircraft provides crucial flight information to pilots during all aspects of aircraft operation. HUD systems have become an essential tool in the cockpit and make aircraft safer when flying in less than ideal conditions. The team was tasked by Honeywell Aerospace to update the technology used in its current commercial aircraft HUD system and to identify and explore the next generation of technology to be developed. The current HUD model supported by Honeywell uses a light source technology more than 100 years old – the cathode ray tube. The current model also requires the use of a combiner, which is an additional pane of glass in the cockpit that the HUD image is projected onto. Through trade studies, testing and analysis, this project will identify an updated image source that uses modern technology (LED, LCD or LCoS) to provide better performance in the aircraft. In addition to the selection of an updated image source technology, the project team has identified a solution for the elimination of the combiner, which makes the cockpit safer by eliminating clutter and fragile material from the environment. The team has identified a method for projecting the HUD directly onto an aircraft windshield through the use of holographic films and optical filters applied to the system. This next-generation technology will allow for more conformal and adaptive HUD systems in the future.

Ducted UAV DevelopmentInterdisciplinary Engineering Design Program

Team 1313: Project SummaryHoneywell requested a production candidate unmanned aerial vehicle (UAV) to assist emergency responders in hazardous situations. Customers of the designed UAV are groups such as SWAT, police and fire departments. The UAV was originally a two motor and two duct system. The team redesigned the entire UAV to host four ducted motors to provide enhanced performance and increased flight time. The UAV has the ability to use an onboard camera and data analytics system to relay information to a ground controlling station. The operator can then use the information and video feed to make real-time tactical decisions in order to limit loss of life and minimize risks associated with any operation. In the event of a motor or flight failure, the UAV has been equipped with an emergency parachute deployment system. This system will deploy to save the UAV from crashing and being destroyed.

Turbine Electric Hybrid VehicleInterdisciplinary Engineering Design Program

Team 1314: Project SummaryThis project is a technology redesign from last year’s mobile test stand project of integrating an Allison 250 turbine engine into a 1977 Triumph Spitfire vehicle. While working with the industrial digital engine controller (iDEC) and the engineers from our sponsor, Tucson Embedded Systems (TES), the primary goal of this project is to use the electrical power generation capabilities of an iDEC-controlled turbine engine to run electric motors powering the vehicle’s drivetrain. Combining an efficient turbine-charging system with a new battery storage system, and implementing a low-cost electronic drivetrain, the system will provide over 60 kilowatts of power for every component of the vehicle. This will be done without the need for an external source, excluding fuel, and turns the vehicle into a turbine-electric hybrid. This new and improved test vehicle will overcome many drivability and usability issues from last year’s design and contribute more information and data to the further development of turbine applications that align with the sponsor’s needs.

Carbon Nanotube Appliqué for Stray Light MitigationInterdisciplinary Engineering Design Program

Team 1315: Project SummaryStray light is a major problem for optical imaging systems, especially when viewing very faint objects in deep space. Image degradation results from excess noise in the form of light rays that were not intended to reach the detector. While stray light can never be totally eliminated, MIT’s Lincoln Lab has proposed that carbon nanotube coatings can outperform currently used diffuse materials when coating baffles and other surfaces in an optical system. If successful, this technology will significantly improve image quality, signal-to-noise ratio, and resolution in astronomical imaging. The purpose of this project is to create a computer model and compare it to data collected from a physical model. The data will be used by the customer to aid in determining the feasibility of using carbon nanotubes for stray light mitigation in space imaging systems. A digital camera attachment was designed and used in conjunction with image processing software and stray light analysis software to analyze the stray light mitigation capabilities of the carbon nanotubes. Metal substrates coated with various black materials were inserted into the attachment and image processing was done for comparison. Vertically grown, multiwalled nanotubes were grown on one set of substrates, while another set had a spray-on nanotube coating. Other coatings used for comparison were Z306 paint, black anodized aluminum, and black chrome.

Solar Panel Cleaning DeviceInterdisciplinary Engineering Design Program

Team 1316: Project SummaryThe goal of this project is to create a system to clean solar panels for team sponsor Sunora Energy Solutions. Fixed-tilt solar panels require a certain amount of access between each row according to the operations and maintenance regulations set out by Sunora’s parent company. These access rows are limited by the shading from neighboring rows of panels and by the width needed to clean the panels. By minimizing the width of the rows between the solar panels, the sponsor can maximize the amount of solar panels that can be placed in a fixed area, or reduce the amount of land required for a certain power output. The team’s goal is to create a device or a machine that can be used to clean the panels while using the least amount of room possible between the panels. The project consists of two main components. The mobile tank unit (MTU) consists of a cart, a water tank, a battery, a control box, and a pump that the user can push between rows. The MTU is two feet wide to minimize the space of the necessary roads. Its job is to transport water and provide power to the cleaning device. The “Zoomba” is a rail-mounted automated cleaning device. It is placed on a rail system mounted on the solar panel support frame, and connected to the MTU for power and water. The Zoomba glides across solar panels on the rail system while spraying water and brushing the panel with a pair of cylindrical brushes. When panels become dirty, power output is reduced, diminishing overall site production.

Healthy Together Systems Engineering ProjectInterdisciplinary Engineering Design Program

Team 1317: Project SummaryThis project aims to improve the overall safety and quality of care for special needs patients who qualify for both Medicare and Medicaid. It is hoped that it will reduce morbidity and mortality, and enhance quality of life and functioning. The program will reduce unnecessary hospitalization, emergency department use, specialty care, and related total costs; integrate medical and behavioral health care management; and improve medication adherence. It will help develop strategies to better identify patients not in the upper cost stratum who are at risk of becoming high users/cost members, and simplify the ability to document best practices of care through team interactions with patients in the home setting. The Healthy Together Care Program (HTCP) has created a very generic database to store patient information in the hope of improving the quality of care of patients in Arizona. HTCP has requested a more advanced digital filing system that will enable it to deliver this care with greater efficiency and specificity. In an effort to accomplish its goals of improving Arizona health care, HTCP requires this database to include a user interface for import of data and generation of printable reports that summarize entire population information and specific patient information.

Clinical Frailty MeterInterdisciplinary Engineering Design Program

Team 1318: Project SummaryClinical frailty is a common geriatric syndrome characterized by slow sit-to-stand transitions, instability, slow limb movement, inordinate gait, low grip strength, exhaustion and unintentional weight loss. The present assessment for detecting frailty of individuals is subjective to these criteria. A new clinically meaningful frailty screening tool is needed to accurately quantify the clinical frailty syndrome, thus translating into earlier diagnosis, better targeted interventions, and more precise measurement of change in frailty parameters with rehabilitation. This project focuses on creating a device, to be worn by an elderly patient, that will ultimately rely on an algorithm that can differentiate between non-frail, pre-frail, and frail patients after performing a sit-to-stand test. Acceleration and gyroscope data will be collected in real time. Key parameters from the sit-to-stand test, such as trunk orientation, velocity and acceleration peaks, and duration will be evaluated to diagnose the patient immediately after conclusion of sit-to-stand test. The vision of this project is to create a device and test that reduce the time and space for frailty tests to be conducted in a clinical setting. If a prototype is developed further, the increased accuracy of diagnosing frailty could lead to prevention of pre-frail individuals becoming frail.

Design of a Cell-Phone Amplification Device for Older Adults with Hearing LossInterdisciplinary Engineering Design Program

Team 1319: Project SummaryHearing loss is a prevalent condition among adults. Hearing aids and other forms of hearing assistive technology (HAT) are expensive and sometimes inconvenient. Smartphones can be used as an inexpensive alternative form of HAT; however, most applications are only available for iOS. Furthermore, the applications currently on the market do not publish their electroacoustic characteristics, and they do not necessarily follow FDA safety regulations. The project team proposes to develop an Android-based HAT application that will consider safety requirements for output intensity and duration, and to provide the electroacoustic properties of interest according to the ANSI S3.22 specification. The proposed solution will tailor the aural output to the needs of the patient by performing a hearing test to determine the extent of their hearing loss. An equalizer will customize the frequency response for each ear accordingly. It will employ both a discrete-wavelet transform filter and spectral subtraction methods for reducing noise.

Novel Reagent Dispense and Dispersion Apparatus for Small VolumesInterdisciplinary Engineering Design Program

Team 1321: Project SummaryPatient tissue samples are sectioned and stained in order to examine cellular composition. Hematoxylin and eosin (H&E) staining is the principal stain used in medical diagnosis. Ventana Medical Systems uses an H&E staining platform to assist in cancer diagnostic solutions. Ventana’s current H&E staining process uses a puddle technique to stain tissue samples. This method uses more reagent than is necessary. The goal of this project was to design and prototype a system to uniformly dispense and disperse micro volumes of fluid on a microscope slide. The team has come up with a process that will uniformly dispense and disperse less than 45 microliters of reagent onto a test slide using an ultrasonic method. The system was designed to reduce the volume of reagent used. Integration of this or a similar method could reduce the cost and waste associated with the staining process.

Automated Leveling ToolInterdisciplinary Engineering Design Program

Team 1322: Project SummaryVentana Medical Systems Inc. has automated the slide staining process of pathology with slide staining instruments. These instruments contain modules that hold batches of slides to be stained. The automated leveling tool (ALT) ensures that slides holding tissue samples are level to within 1 arc minute. If the slides are not level the processing liquids will wick off the tissue sample because they are only held on the slides (and tissue samples) by surface tension. Currently this leveling is done manually. Technicians adjust screw mounts to ensure that the whole instrument is level along with its modules. The modules are located within the instrument and hold the trays that contain the tissue slides. The actual leveling is checked with multiple spirit levels. The ALT automates the leveling process, providing three main benefits: the modules can be leveled more accurately, more consistently, and more quickly.

Bike Radar ProjectInterdisciplinary Engineering Design Program

Team 1323: Project SummaryThe bike radar project started with summer interns at ViaSat working to create a product that could alert cyclists to potential collisions from behind with other road users. These interns completed the printed circuit board (PCB) and housing design, but it was this team’s job to create a fully functional prototype. To accomplish this goal the team needed to program the PCB and design and code an iPhone app that would work in conjunction with the bike radar unit. In programming the microcontroller, the team’s electrical engineers had to develop digital signal processing algorithms that could read the data from the radar and determine whether a crash was imminent or not. This output could then be sent to the iPhone to alert the user of the potential collision. The team also refined the housing design to perform well in all conditions, and to make it ready for a transition to mass manufacturing should ViaSat take this product to market in the future. The final product is a fully functional prototype of a bike radar unit that works in tandem with an iPhone app to alert cyclists of potential collisions with road users.

Exploring 3-D Printed RFID for a Specific ApplicationInterdisciplinary Engineering Design Program

Team 1325: Project SummaryThis project develops a process for 3-D printing radio-frequency identification tags, including conductive interconnect and antennas. The process handles printing thermoplastics and a conductive material simultaneously with a novel technique. The process was used to print a demo RFID tag for a survivable security application. The project consists of two major components: a modified print head for a Makerbot Replicator 2X, and a custom-printed RFID tag. The print head modifications add conductive material capability to the 3-D printer. After extensive characterization of the modified print head using specialized designs, the printer was used to print antennas for testing the RFID tag design. The team designed and implemented a 915 MHz band antenna to integrate with a commercial RFID and data logging IC. The antenna design was completed using HFSS and ADS simulation, and was tested using a prototype built with a 3-D-printed substrate and copper tape. To demonstrate and test the system, the printed tag was tested with a commercial RFID reader. Custom Python software is used to communicate with the RFID reader, and then implement application-specific logic. The project demo uses this capability to demonstrate an RFID security tag embedded in the structural plastic of a consumer product. The 3-D-printed tag is able to replace a plastic component of the product with a replica containing an RFID tag. The software system tracks the tag and sends an alert when it is detected missing.

Quiet Super First Class SuiteInterdisciplinary Engineering Design Program

Team 1326: Project SummaryThe main objective of this project is to provide maximum comfort for airplane passengers within first class suites built by B/E Aerospace. The primary goal is that the system incorporates a sensor to detect the passenger’s state. If the passenger’s eyes have been closed for more than 10 seconds, the system will detect this and send the appropriate signals for the lights in the suite to dim. Once the passenger has opened his or her eyes for more than 10 seconds, the system will recognize that and begin to slowly turn the lights back on. The secondary goal is to create an active noise-control system for a super first class airplane suite. The system will use a microphone to detect the noises that are generated within the suite. Then the data detected by the microphone is sent to the computer where various filters are programmed. These programs filter the frequency range that is desired to be cancelled and generate a wave that is out of phase with the original sound wave detected by the microphone. When these two waves align, they cancel each other out and achieve silence.

Vision System for Automotive Cluster (Dashboard)Interdisciplinary Engineering Design Program

Team 1328: Project SummaryThe goal of this system is to perform quality control of an automobile dashboard by checking for defects. To do this the team set up the dashboard in a dark room containing cameras that can image all viewable parts of the dashboard cluster. The cameras and dashboard are connected to a computer outside of the dark room. Through the computer, the backlight of the dashboard is turned on and the cameras take a series of images. The images are then analyzed for defects that cause them to differ from an ideal cluster. If each region of the cluster is free of defects, the dashboard is a “pass,” whereas any contaminants or pixel defects will make the dashboard a “fail.” The design of this system should perform well enough to replace a human quality control worker, which would save Continental Automotive in labor costs while improving the results of this quality control component of the dashboard assembly. The team has designed the dark room and cameras with a resolution of 200 µm, which is equivalent to the smallest detail discernible to the human eye.

Bezel Protective Mask 3-D Printing ModelingInterdisciplinary Engineering Design Program

Team 1329: Project SummaryContinental Automotive Systems currently uses bezel protective masks to prevent scratches or damage to three different stereo faces during manufacturing. The bezels are outsourced to an external supplier and fabricated using a computer numerical control machine. Due to the high cost of these parts, Continental would like to bring production in-house and use 3-D printing. The team designed new mask protectors within SolidWorks to be fabricated with a 3-D printer. The new masks are to be used by the pre-existing test and assembly fixtures of the car radios. The team also researched industrial 3-D printers that can accomplish these tasks efficiently, and selected a 3-D printer capable of printing these masks consistently and economically. To guarantee the successful integration of the new masks, the team printed its new versions on a personal 3-D printer and tested their performance against the old masks. The new masks coupled with the 3-D printer are estimated to reduce the cost of each mask from around $250 to around $10. Additionally, the applications of the selected 3-D printer will extend beyond the bezels, to include additional functioning parts for other projects as well as prototypes and scale models for presentations.

Development of a Surgical Spine Simulator and TesterInterdisciplinary Engineering Design Program

Team 1331: Project SummaryNeurosurgeons at the University of Arizona Medical Center are interested in observing how various spine fixation surgeries affect patient outcomes and quality of life. This design team has built a system that can test the biomechanical properties of cadaver spines before and after surgical intervention. The system can apply user-specified parameters to perform physiological-like loading on the spine using motor control, which can be used to measure displacement. It will use strain sensors mounted on a custom-built load cell to measure force. The data is then presented to the user in a visual display, including graphs of force versus displacement. Repeated loading is supported in this team’s device, so surgeons can observe the long-term effects of their procedures on spine flexibility and stability. Ultimately, this device will improve the lives of patients by creating a customized, quantitative approach to assessing spinal surgical outcomes.

Wireless Flow Sensor Using GMR Magnetic Sensors for Cerebral Spinal FluidInterdisciplinary Engineering Design Program

Team 1332: Project SummaryHydrocephalus is a common medical condition characterized by an excessive build-up of cerebral spinal fluid (CSF) in the brain, increasing intracranial pressure. A common treatment for hydrocephalus involves the implantation of a ventriculoperitoneal (VP) shunt in the ventricles of the brain that drains to the peritoneal cavity (belly area). Because 80 percent of shunts fail after implantation, there is a need for noninvasive VP shunt diagnostics. Current VP shunt diagnostics are limited to invasive surgical procedures and pressure measurements. Accurate flow measurements will help neurosurgeons understand hydrocephalus, its impact on the brain, the events leading up to shunt failure, and the causes for shunt failure. To address this issue a wireless flow meter has been designed and created to measure the volumetric flow rate of CSF. The device contains a battery-powered sensor and electronic circuit that converts beam deflection due to fluid flow into a voltage change. The magnitude of the voltage change is directly related to the volumetric flow rate. The data is wirelessly transmitted to a computer, tablet or smartphone where the volumetric flow rate is displayed.

The meter can also identify which utility in a household is broken or consuming more energy than desired. This smart grid technology can be used in meters at homes, businesses and factories. The team’s objective was to design and build a system using industrial instrumentation and equipment to detect the power consumption of individual household utilities. For the system to be user friendly and interactive, the team also designed a graphical user interface to control the system using personal computing technology. To display relevant data to the user, the team created a nonintrusive load-monitoring algorithm to disaggregate multiple power loads from a single measurement. The team is aiming to create a system that combines an easy-to-install smart meter with analysis software.

Electromechanical Shaft Disconnect for GeneratorsInterdisciplinary Engineering Design Program

Team 1336: Project SummaryThe objective for this team was to design an electromechanical system to disconnect an aircraft’s generator from its gearbox without causing damage to either of those components. Currently, if an aircraft’s generator fails it disconnects from its gearbox by shearing a shaft once the forces get too great. Although effective, this process does not allow disconnection before damage is caused. The design and model built for this project is a proof of concept: proof that there is a system that could be implemented to disconnect at any moment and not just when a shaft shears in half. To achieve this, a three-part system was implemented: an input shaft coming from the gearbox (and engine for this team’s test purposes); an output shaft going to the generator (nothing is attached to this side in this demonstration); and a solenoid armature. The input and output shafts transfer the speed and torque to each other through the use of steel balls placed between them. The balls are held in place by holes in the input/output shafts and by the solenoid armature. When a disconnect of the two shafts is necessary the solenoid armature pulls back and releases the steel balls upward and out of the input shaft holes. This creates a clean disconnect between the two shafts and allows the input shaft to continue running.

Cabin Pressure Control System Pressure Rate SensorInterdisciplinary Engineering Design Program

Team 1337: Project SummaryThe objective of this project is to create an accurate, high-precision aircraft cabin pressure rate sensor at a fraction of the cost of currently used sensors. Aircraft cabin pressure control systems depend on accurate, reliable pressure and pressure rate-of-change data to provide a safe, comfortable environment for aircraft passengers and crew, making the cabin pressure rate sensor a critical component of the system. Current Honeywell systems use a single, high-precision sensor to measure pressure and rate. While these sensors are accurate and reliable, they are expensive. The new design incorporates an array of multiple lower cost sensors. A central processor simultaneously monitors all sensors in the array and implements specialized algorithms to verify and combine the pressure values into a single, highly accurate result. The processor then computes the rate of pressure change, and both pressure and rate are transmitted digitally to the cabin pressure controller. The diversity of pressure readings inherent in this design contributes to improved accuracy and sensor availability, and provides built-in checks to maximize dependability.

Numerous cities, counties and states classify the reclaimed water used by golf courses as nonessential. This has caused the water bill for golf courses to increase substantially. Currently, the average golf sprinkler nozzle has a distribution uniformity (DU) of 70 percent. This uneven watering is causing brown patches of grass in the sprinklers’ spray radius. This project focuses on improving two of the three measures of sprinkler uniformity, DU and scheduling coefficient, for two of the nozzles currently included on Rain Bird’s 751 series rotor from 80 to 88 percent at 80 psi. The second goal for this project is to create a new violet nozzle for the 751 rotor that can spray 91 feet at 80 psi.

Compression vs. Quality for Payload HD VideoInterdisciplinary Engineering Design Program

Team 1339: Project SummaryAs military test ranges such as the U.S. Army Yuma Proving Ground (YPG) move from analog to digital recordings, they have adopted IRIG 106 Chapter 10 recording standards. The Chapter 10 recording standard uses video compression algorithms to decrease bandwidth, which can reduce image quality. A trade-off is required to minimize file size while maximizing image fidelity. This becomes a bigger challenge as video bandwidth grows with increased use of high-definition video. At YPG, high-definition video is used on fixed and rotary wing aircraft as well as unmanned aerial platforms for target recognition and impact scoring. The video is recorded, or transmitted to the ground for real-time display, or both. The goal of this design project is to define the interaction between compression settings that minimize bandwidth for recording and transmission and maximize image fidelity for high-definition video recorded in Chapter 10 format. Additionally, this project addresses how those compression settings affect how the video is displayed on monitors and documents optimal monitor settings. This trade-off analysis can be used to determine optimal compression settings for the specific mission at hand.

A High-Throughput Small-Angle Light-Scattering System for Soft Tissue QuantificationInterdisciplinary Engineering Design Program

Team 1340: Project SummaryThe Soft Tissue Biomechanics Laboratory (STBL) at the University of Arizona is focused on solving biomedical-related problems using experimental and computational techniques in biomechanics. The STBL’s small-angle light-scattering (SALS) device is used to assess the preferred fiber orientation and microstructure within soft tissues and tissue engineered biomaterials. The pre-existing system imaged fiber orientation data in a high-throughput manner from tissue samples on microscope slides using a helium-neon laser, and required extensive human interaction to place, align and image each slide. The team was tasked with redesigning the system, creating an auto-alignment algorithm for sample locating, implementing a bulk slide loading system, and minimizing any unwanted stray light reflections. The redesigned system uses small electronic grippers to grab slides one at a time from a custom-designed cartridge that advances on a mechanical rail, and uses precision optical components to ensure desired and accurate laser alignment. The team also wrote thorough documentation for the updated SALS device to ensure longevity of the system’s hardware and software.

Formula SAE Stressed Engine/Hanging DifferentialInterdisciplinary Engineering Design Program

Team 1342: Project SummaryThe FSAE stressed engine/hanging differential system is a complete redesign of the back end of the WF14 FSAE car. The goal of the project is to create a lighter, stronger and ultimately more competitive race car. The stressed engine will function as a load-bearing part of the car, removing unnecessary tubing structure from the rear end, allowing for quicker service time. The hanging differential will allow for a quick sprocket change and chain tension to shorten pit stops. Above all, the reduction of frame members and complete removal of a differential cage will reduce weight, producing a faster accelerating, quicker turning, harder stopping car. To verify analysis and monitor the car on the track, a data-acquisition system will be fitted onto key components of the engine and differential mounts to track strain through different loading scenarios seen on the track. This will be done using strain gauges, GPS and accelerometers. The WF14 will compete with colleges from all over the world in June 2014 at the FSAE West competition in Lincoln, Nebraska.

Centralized Application for Secure Data TransferInterdisciplinary Engineering Design Program

Team 1343: Project SummaryNaval Reactors programs are responsible for the safe and reliable operation of the U.S. Navy’s nuclear propulsion program. During a 2006 “Managing Sensitive Information” review conducted by the U.S. Government Accountability Office (GAO), the GAO found a lack of oversight and inconsistent implementation of DOD’s information security program guidelines. These inconsistencies led to weaknesses in areas such as training, standardized procedure control, security classification management, and auditing procedures. The Centralized Application for Secure Data Transfer (CASDT) is a software application developed to address the weaknesses described above, specifically with respect to distribution of classified documents. CASDT will facilitate the request of classified documents to employees through a standardized process. The designed application ensures an increase in program oversight and accountability for classified document requests throughout the document’s lifecycle, to include submission request, request review, and request audits. Auditors will have access to all previously submitted requests and the ability to ensure the strict compliance of the document-transfer processes.

Linear Average Launch Speed Measuring DeviceInterdisciplinary Engineering Design Program

Team 1344: Project SummarySensintel tasked this group with designing a way to measure the velocity at which launched objects leave the company’s rail-based launching system, while logging data that could be used to plan maintenance and predict component failure. The company wanted a way to quickly and accurately measure the velocity of a launched object as it leaves the rail. Some of the launched objects are equipped with a GPS system, but this does not respond quickly enough to provide an accurate velocity at launch. Due to the large amount of stress experienced by the launching device, pieces of the system fail and require periodic maintenance. By cataloguing the launch events, the team’s device will provide information that indicates the lifecycle and necessary upkeep for each individual launcher. The device designed to accomplish these goals operates on a simple principle. The time it takes the launcher to move over a set distance is measured, and the velocity is calculated. In addition to the velocity data, the device collects number of launches to aid in predicting launcher failure and in establishing maintenance cycles.

Image-Guided Computer-Controlled Delivery of Therapeutic Focused UltrasoundInterdisciplinary Engineering Design Program

Team 1345: Project SummaryCurrent techniques for delivering drugs to the brain are invasive and risky to the subject. The goal of this project is to develop an automatic positioning device to implement a minimally invasive technique for efficiently delivering drugs to the brain. The design involves a magnetic resonance imaging (MRI) compatible, image-guided automatic positioning system for delivering MRI-guided functional ultrasound (MRIgFUS). The positioning system includes a graphical user interface with motor control, ultrasound activation, and an animal cradle apparatus. Drug delivery can be accomplished by breaking the blood-brain barrier using MRIgFUS. The lipid-coated microbubbles and the desired drug will be injected into the rodent’s tail. Then focused ultrasound will be applied to the brain, which will oscillate the microbubbles. These oscillations will disrupt the tight junctions between capillary endothelial cells, which will allow the drug to move into the brain through the widened gap.

Microfluidic Devices for the Isolation and Characterization of Circulating Tumor CellsInterdisciplinary Engineering Design Program

Team 1346: Project SummaryThe scope of this project is to create an affinity-based microfluidic device that can capture and isolate circulating tumor cells (CTCs). The proposed system is a two-step process involving two channels, each coated with anti-cadherin-11, which allows for easier enumeration and characterization of the CTCs. The device should have 99 percent specificity and 95 percent sensitivity while maintaining cell viability. Specific attachment and detachment profiles for the capture of CTCs have been created by the team to accomplish the objectives set by the project sponsor. The goal of this project is to produce a design that can eventually be used to test patient blood samples in a clinical setting and be used as an alternative to current biopsies for detecting cancer in patients; however, during the design process, a simplified mixture of target and nontarget cells will be adopted in order to test the basic capturing function of the device.

Minimally Invasive Image-Guided Vascular AnastomosisInterdisciplinary Engineering Design Program

Team 1348: Project SummaryThe goal of this project was to design a bifurcating stent that used existing technology related to vascular stents, wires, and catheters to offer an alternative to surgery. All of this is accomplished through the skin, without sutures, employing the use of medical imaging guidance such as ultrasound, computed topography scanning, or X-ray fluoroscopy. The resulting stent aims to solve the clear and common problem in daily practice of poor access to vascular structures for diseases such as diabetes, renal failure, limb salvage, vascular diseases, or ischemia. The final product delivered by the team is a three-dimensional model created with SolidWorks, model analyses, necessary protocols and an enlarged three-dimensional printed prototype that demonstrates satisfactory proof of concept. These delivered models will then be used by the sponsor to create a fully functional Nitinol and PTFE bifurcating stent.

Simulated Gravity SuitInterdisciplinary Engineering Design Program

Team 1349: Project SummaryThe simulated gravity suit (SGS) is a wearable mechanism designed to passively provide resistance to the motion of the user. The resistance provided is tailored to prevent the bone and muscle degradation encountered by astronauts on long missions. While in space, the human body does not have to work against the force of gravity. In response, the body reduces bone and muscle mass to adapt to the environment. This poses a health threat for astronauts when returning to an environment with gravity, such as Earth or Mars. The SGS uses a network of resistive elements, primarily elastic bands, that provide compression to the spine and resist the motion of the user. These components apply forces to the body intended to replicate the forces exerted by gravity on Earth. Replicating the effects of gravity helps maintain healthy bones and muscles. The health benefits provided by the SGS will help enable extended missions in space, such as a manned mission to Mars. Because of this, the materials used have been selected for comfort during continuous wear. Additionally, this device has potential for Earth-bound applications in physical therapy and rehabilitation.

Multichannel EMG Wearable Technology to Identify Frailty in Older AdultsInterdisciplinary Engineering Design Program

Team 1350: Project SummaryThe goal of this project is to use multichannel electromyography (EMG) signals to determine the muscle fiber conduction velocity (MFCV) of a patient’s bicep. The device will be tested in a clinical setting on patients of various frailty levels to determine if there is a correlation between MFCV and frailty. The system measures the action potential propagation along the surface of the bicep using five strategically placed reusable electrodes. The electrodes are attached to a custom-made sleeve placed around the patient’s arm. The contraction of the bicep generates an electrical signal that is detected by the EMG electrodes and transferred to a data acquisition system, which exports the raw data to a computer, where software created on Matlab processes the signal. The software identifies signal propagation of an action potential across four channels. Using the interelectrode distance and propagation, the software computes the MFCV, and displays it on the user-friendly interface for a health professional. The goal is for a health professional to use this MFCV value to assist with the diagnosis of a patient with frailty symptoms.

CLARITYInterdisciplinary Engineering Design Program

Team 1351: Project SummaryCLARITY is an electrochemical process that creates a tissue-hydrogel hybrid from biological tissue. The tissue-hydrogel hybrid then enables molecular and optical interrogation of large assembled biological systems. Being able to optically interrogate large biological systems, such as adult mouse brains, can allow researchers to obtain systemwide and molecular-phenotype information at the resolution of a single cell. In this regard, researchers at the University of Arizona are currently interested in using the CLARITY process in neuroscience studies. However, the CLARITY process is time consuming, expensive, and challenging to reproduce, so this design team identified the process workflow and analyzed which steps of the process could be optimized. To that extent, the team has attempted to standardize the process by using 3-D printed components, reduced cost by using alternative equipment, and used reverse-engineered chemical solutions to shave costs. The result of the team’s efforts is a process that is cheaper and as effective as the originally proposed CLARITY process. The team’s optimized CLARITY process will be open-sourced on a forum to allow researchers everywhere to use, modify and critique.

Smartphone App Integrating SENSUS to Manage Painful Neuropathy in Diabetic PatientsInterdisciplinary Engineering Design Program

Team 1352: Project SummaryThe goal of the project is to create an interactive smartphone application that will display a suggested therapy schedule for patients with painful diabetic neuropathy, helping them use the SENSUS device to maximize pain relief. SENSUS is a transcutaneous electrical nerve stimulator that causes biochemical changes in the spinal cord to relieve pain. Pain from neuropathy typically starts in times of inactivity due to lack of sufficient blood flow to peripheral nerves. The SENSUS device removes this pain, allowing the user to increase their activity and halt the progression of the disease. This project combines this technology with an external activity monitor to determine an effective therapy schedule based on correlations between the patient’s use of the SENSUS and their daily activity. This schedule is viewable online and in a smartphone application. Patients are able to adapt the schedule in the application to predict times when they will feel pain based on their typical activity levels, so they can start therapy before the pain becomes unmanageable. This will allow the patients to become proactive about preventing pain, instead of reacting to pain. The program also generates reports for the patient’s physician, ensuring the physician can monitor the progress of therapy and remain in control of the patient’s medical care.

Motion Correction for PET and SPECT Using Wearable SensorsInterdisciplinary Engineering Design Program

Team 1353: Project SummaryThe team designed a wearable sensor system that can record head movements and correct for motion-induced image problems in positron emission tomography (PET) and single photon emission computed tomography (SPECT) imaging. During PET and SPECT imaging any movement of the head can cause the final images to blur and become unreadable. The team’s system tracks a patient’s head movements during an entire scan. After the scan is complete the software corrects the raw images using the collected motion data. This is a useful tool for doctors who might be imaging a patient with Alzheimer’s or Parkinson’s, when asking the patient to remain completely still is not feasible. The team hopes the system can make this process easier for doctors and patients while resulting in higher quality medical images.

Roof Surveying VehicleInterdisciplinary Engineering Design Program

Team 1354: Project SummaryMaximizing the concentration of solar modules on a rooftop is critical for achieving a positive financial return. To optimize the solar output of proposed systems, SOLON must ensure that the coordinates and layout of the rooftop are accurate. The project team has created a prototype mobile imaging system that will perform a rooftop survey. This is achieved by creating a roof-surveying vehicle that can be manually placed on a rooftop and then controlled by an operator who follows it around the roof. The operator will not be required to possess any programming knowledge or mechanical knowledge, but will be given an area or path to follow and will simply drive the vehicle within the boundaries using a preprogrammed movement-control device. The data is stored automatically on an internal hard drive inside the vehicle chassis and later imported into AutoCAD by SOLON employees. Once the data is stored to the hard drive, the survey is complete and the requirements have been met. By developing a vehicle that can accurately and quickly map a rooftop, SOLON can optimize the solar output (energy) of its systems.

Dynamic Aberration CorrectorsInterdisciplinary Engineering Design Program

Team 1355: Project SummaryCurrent adaptive optical devices provide solutions that are very high cost and consume large amounts of tabletop space. This device is simply inserted into small tabletop optical systems and is easily tunable with a unique mechanical design. The device is completely free from electronics, computers, and software, making it simple to install and use. The design makes use of counter-rotating phase plates that use the mutual orthogonal nature of polar Zernike polynomials to dynamically target and eliminate specific aberrations. By spacing the plates closely together and applying a well-defined amount of counter-rotation, the device can induce a wide range of specific aberrations. A user-friendly and tunable mechanical housing was designed and fabricated to achieve the counter-rotation of the closely spaced optical plates.

Pitching Mechanism for Airfoil Dynamic Stall ExperimentsAerospace Engineering

Team 1357: Project SummaryThe goal of this project is to build a pitching airfoil that can be used to study the characteristics of dynamic stall over an airfoil. The design for the pitching mechanism consists of an electric motor attached to an airfoil control shaft via a flywheel, pushrod and pivot arm. The angle of attack is measured by an optical encoder on the airfoil shaft in order to be used in conjunction with a variable frequency drive to control the speed of the motor, and thus the pitching frequency of the airfoil. To control the initial angle of attack of the airfoil, pushrods of different sizes are used. To control the range in which the airfoil oscillates, holes have been placed in precise locations along the pivot arm, and the motor is on tracks that move it so the pushrod is perpendicular to the pivot arm.

Sabino Canyon Unmanned Aerial VehicleAerospace Engineering

Team 1358: Project SummaryThe goal of this project is to develop a portable flying wing unmanned aerial vehicle (UAV) with short takeoff and landing capability. The primary motivation in developing this UAV system is to have a platform with the ability to assist ground teams for search and rescue missions. With a camera system onboard, park rangers and rescue teams can send the UAV to search a wide area and find the location of a lost or injured hiker, reducing the overall time needed to find the hiker. In addition, the configuration of the sensors can be modified to allow for different mission capabilities.

The flying wing is constructed from strong, lightweight composite material, which reduces the overall weight and enables the UAV to meet the range requirements of this project. A short takeoff launcher was developed to allow the aircraft to get airborne in a minimal distance while avoiding immediate obstacles. The UAV is also outfitted with an autopilot, allowing the aircraft to fly autonomously to designated waypoints, eliminating the need for experienced pilots.

Soaring Design TeamAerospace Engineering

Team 1360: Project SummaryThe goal of this project was to create and code a logic structure that allows an unmanned glider to gain altitude autonomously by using the natural energy of thermals. This allowed an unmanned aerial vehicle (UAV) to stay airborne for longer without using additional electrical energy. In the design and operation of UAVs, nature is typically seen as a hindrance rather than a help. This project sought to reverse that by turning the sun’s energy into useable energy in the form of altitude. This was accomplished by circling around thermals – rising pockets of air – which enable gliders to gain altitude by rising with the surrounding air. Birds and human glider pilots have long been taking advantage of these benefits by a process called “thermalling.” The challenge of this project was to have a UAV autonomously detect the presence of a thermal without the instinctive senses used by birds and human glider pilots. Instead, the team’s algorithm relies on data received through an onboard GPS and pitot tube, with which both the airspeed and altitude can be measured. By combining these two key pieces of data, the glider can autonomously determine whether or not it is in a thermal. Once a thermal is detected, the glider switches into a “thermalling mode” and circles around the predicted center of the thermal. Efficient use of this algorithm could increase the flight time and decrease the energy consumption of any UAV system.

Design of a High-Powered Rocket Altitude Targeting SystemAerospace Engineering

Team 1362: Project SummaryThe goal of this project was to create a system that uses solid rocket motors to loft a payload to a specific altitude. Through research a two-stage rocket was determined to be the best design for this task. Onboard electronics compare real-time altitude and velocity data with stored simulations and determine the optimum time to ignite the sustainer stage and separate the two stages. The payload is a 10-pound weight and initially was estimated to make up 25 percent of the weight of the rocket. To reduce weight, it was determined that the body tube would need to be constructed entirely of carbon fiber composite material. To increase attitude, drag was reduced in every area possible. The nosecone was constructed to give the lowest drag possible and a tailcone was added to decrease drag due to separation by 40 percent. The fins were constructed with an airfoil cross section to reduce their drag contribution by 70 percent. To increase structural stability the fins, tailcone and motor mount were printed as a solid piece using a high-performance thermoplastic material.

The school participates in Pima County’s Joint Technical Education District program, which allowed a greenhouse to be built on the school grounds for furthering education. However, the greenhouse was being underused because the school was only growing seasonal flowers a few times a year. An operational greenhouse provides great educational opportunities as well as the capability to produce healthy and delicious food for the students. The administrators and teachers at the school district recognized the opportunity to implement a hydroponic system for the greenhouse, with the goals of producing food for the cafeteria and integrating the greenhouse into the educational experience. The design team opted for an aquaponics system because it maximizes the educational opportunities for the school while providing crops and fish in a very sustainable system. The aquaponics system can sustain 120 pounds of tilapia and about 15 koi. The crop-growing part of the system will produce 24 heads of lettuce per week from an 8-by-8-foot floating raft table and provide additional room to grow more than 100 herb plants in an 8-by-4-foot floating raft system, and any other plants in a 10-by-8-foot media bed. Remote monitoring capabilities have been built into the system to allow online monitoring of the aquaponics systems.

Solar Power Capable Archimedes’ Screw PumpAgricultural and Biosystems Engineering

Team 1365: Project SummaryThe goal of this project is to design, build, and test two Archimedes’ screw pumps with varying performance requirements and size constraints. These pumps will be used to pump algae in the algae raceway integrated design (ARID) pilot-scale raceway. The constraints for the first pump are that it must be able to pump at 40 gallons per minute, and must be able to lift the water five feet. The second pump must run at 170 gallons per minute and lift the water two feet. The team designed these pumps to be as efficient as possible, and used a flow-rate estimation model based on extensive research to obtain the goal pumping rates. Further, the pumps have the potential to take advantage of solar power. Archimedes’ screw pumps are ideal for moving the algae in the ARID raceway because they minimize shear, which prevents algae cell lysis prior to harvest.

Concentrating Sweet Sorghum Juice Via Reverse OsmosisAgricultural and Biosystems Engineering

Team 1366: Project SummaryCorn’s emergence as an energy crop has been criticized due to its increased price as a food commodity and the resource-intensive cultivation it requires. Sweet sorghum could economically replace corn as a producer of biofuel because it has higher water use efficiency and is not a food crop. Current production capabilities allow sweet sorghum juice to be extracted from stalks with a sugar concentration of about 7 percent. For sweet sorghum to be used competitively in ethanol production, sugar concentration needs to be 18-20 percent. The project team created a pilot-scale reverse osmosis system to concentrate the solution from the University of Arizona’s sweet sorghum diffusion extraction unit. The system includes a prefiltration stage coupled with a series of reverse osmosis membranes. The prefiltration component removes dissolved solids from the raw sorghum juice, decreasing system maintenance requirements. The main component of the system is the series of reverse osmosis membranes that remove water, increasing sugar concentration. At full scale, the system would be able to process one acre per hour, making it economically competitive with corn in the alternative energy market.
