  • Types of UAVs UAV = Unmanned Aerial Vehicles UAS = Unmanned Aircraft Systems 1. Multi Rotor 2. Fixed Wing 3. Helicopter

    Hartman & Bland (2016) 4

  • UAV Applications 1. Military Reconnaissance 2. Agriculture Surveying 3. Construction Safety monitoring,

    surveying, topographical maps 4. Delivery of Goods Amazon, Virginia

    Tech Chipotle 5. Various Career Opportunities

    5

  • UAV Research at UMES Chris Hartman Aviation

    Science Program in collaboration with Department of Agriculture

    6

    K-12 Outreach - Collaboration with NASA UAS Competitions

    TEECA Competitions

  • UAV Regulations FAA defines aircraft as, Device used or

    intended to be used for flight in the air. Drones

  • UAV Safety 1. Safety Glasses worn by all (COMAR) 2. Dont overcharge batteries 3. Establish and enforce a Safety Zone 4. Create Safety Checklist 5. Blade Guards when possible, disconnect power until

    ready 6. Debrief with entire group 7. Establish flight communication protocol 8. UAV safety activities

  • 3D Printing the Drones Thingiverse: Thing 435484 or 681232 Low Quality Print Hollow & lighter weight Assemble Parts, Convert to STL file

    17

  • Dont Have a 3D Printer? No Problem!

    What cheap alternative materials could you use?

    Perfect for prototyping!

  • Testing and Troubleshooting The Wright Brothers first flight lasted only 12

    seconds and went 120 feet

    19

  • Testing and Troubleshooting

    20

  • Testing and Troubleshooting The Wright Brothers first flight lasted only 12

    seconds and went 120 feet

    21

  • Testing and Troubleshooting Propellers specific pitch & installation

    location Soldering extremely difficult Motors hot glue or they will spin Controller Sync and adjust propeller control

    as needed 22

  • Demonstration

  • Integrating STEM Concepts Dronecurriculum.net

    Free Sample Unit (see handout) Science: Bernoullis Principle, Equilibrium,

    Aerodynamics, Lift, Drag, Acceleration, Momentum

    Math: Pythagorean Theorem, Lift, Drag, Acceleration, Momentum

    Technology: Aerospace Engineering, Materials Processing, Engineering Design, Electronics

  • Integrating STEM Concepts

    25 Maley (1984)

  • Integrating STEM Concepts

    26 Maley (1984)

  • Integrating STEM Concepts

    27 Maley (1984)

  • Integrating STEM Concepts: Example Questions

    1. A drone with a mass of 4 lbs. is lifting a small box with a force of 5 newtons. What is the acceleration of the drone? (Hint: 1 lb = 0.454 kg).

    2. After weighing your drone, calculate its momentum. Assume the velocity is 0.75m/s. (Must convert weight to kilograms) [1g = 0.001kg].
