Flight Readiness Review
March 2005
Vehicle Criteria
Testing and vehicle design
Bulkheads: 9-Ply ½” birch plywood made by Public Missiles, Ltd or ¼ inch aircraft plywood
Tests completed:Parachute TestingEjection Charge TestingGround Control ExperimentTesting of Electronics
Fins: 5-ply 8 inch Aircraft grade Plywood/ Fiberglass sandwiches2 Part Expanding FoamEpoxy mixed with Kevlar Pulp
Vehicle Criteria
Recovery
Tubular Kevlar & Tubular Nylon:Uses: to connect the Drogue and Main Parachutes to the rocket bodyLocations of Use: Two U-bolts where both the drogue and the main ejection charges (Tubular Kevlar) Tubular Kevlar to the Parachutes (Tubular Nylon)
Amounts: Tubular Kevlar: Two 5 ft lengths Tubular Nylon: Two 60 ft lengths One 30 ft length One 20 ft length One 10 ft length
Recovery
Parachutes:
• Main Parachute: Public Missiles PAR-120 22 ft/s
• Drogue Parachute: Top Flight Recovery Crossfire 36" 75 ft/s
Vehicle Criteria
Payload Integration
Vehicle Criteria
Bulkheads:Three bulkheads placed into the payload bay in orderto hold the angle, stabilize the sensors andprotect the sensors.
Cap:Made of a bulkhead and two different sizes of coupler tubing, designed to protect the sensorsduring ascent and to trigger the LabPros to start theexperiment.
Payload Integration
Vernier LabPros: Used to collect and record
the data from the sensors.Sensor Clusters:Two clusters of 3 sensors(1
UVA, 1 UVB, 1 light sensor)
Vehicle Criteria
Experiment Concept
Payload Criteria
• Successfully triggered both of the LabPros • Properly record accurate data from all three
sensors• Data collected shows a trend between
UVA/UVB and altitude
Mission Success Criteria:
The experiment is designed to help skiers,snowboarders, and other mountain activitiesenthusiasts to be able to better protect themselvesagainst the Ultraviolet Radiation that they are exposed to.
Science Value
Payload Materials:• 3 Vernier UVA sensors• 3 Vernier UVB sensors• 3 Vernier Visual Light
sensors• 3 Vernier LabPros• 12 new AA batteries• Record Turntable
Payload Criteria
Design of Payload
Reasons for Design:
Angles: The angles are used to help reduce the effects of the Drogue Parachute on the experiment.
Bundles: The reason that we used sensor bundles is because the three scientific values that are being collected in our experiment can vary depending on direction and angle therefore bundles are used to standardize the data.
Payload Criteria
AssemblyPayload Criteria
Throughout the assembly of this entire rocket (including, and especially, the payload) extra care has been taken to ensure an accurate assembly of all parts.
Overall Rocket Design Assembly
Safety and Quality Assurance
Launch Operations Procedure
To ensure the safety and quality of this project we have:• Researched all necessary background information• Planned out all work before beginning assembly• Had two or more team members working on or watching all
aspects of the building process• Paid careful attention to all details
Calendar
• April 4, 2005 - Finish construction of main rocket
• April 23, 2005 - Launch SLI Jr. rocket in Huntsville,
Alabama
• May 31, 2005 - Complete and submit SLI Jr. Report
