Hang Seven Launch Readiness Review

This mission overview outlines the launch readiness review conducted by Lucas Migliorini and team, focused on building three Geiger counters to measure gamma radiation as altitude increases. The design features a hexagonal structure with a foam core and thermal insulation, utilizing aluminum and carbon fiber tubing to assess their effectiveness in radiation reduction. The testing phase includes various structural and environmental tests, yielding insights into the devices' durability and sensor reliability. The group aims to enhance data accuracy while preparing for mission execution.

  1. Hang Seven Launch Readiness Review Lucas Migliorini, Becca Lidvall, Paul Smith Chase Goodman, Ethan Hollenbach, Nikhil Desai, Abby Caballero, Sierra Williams November 26, 2012

  2. Mission Overview •Build three geiger counters •Measure Gamma Radiation as Altitude Increases •Test the effectiveness of aluminum and carbon fiber on reducing radiation levels

  3. Design Overview • Hexagonal Design • Centripetal Acceleration • Foam Core • Thermal Insulation • Geiger Tubes • One will be covered with Carbon Fiber Tubing • One will be covered with Aluminum Tubing • One will not be covered, as a control • Arduino • Will control all sensors and Camera

  4. External Diagram Camera on/off Camera On/Off-Arduino

  5. Internal Diagram Camera Batteries Heater Geiger Counters(3) Arduino with Sensors

  6. Test Results Part 1 Geiger Counters (Oscilloscope Reading):

  7. Test Results Part 2 Key Orange -Temperature Green - Humidity Blue - Pressure Red/Purple/Gray - Accelerometer Other Internal:

  8. Key Orange=Accel X Blue=Accel Y Green=Accel Z Sensor Test Cont.

  9. Internal: Dry Ice Test • Dry ice test results were inconclusive • We plan to look into the problem and do more testing to ensure that the internal components can withstand the temperatures they will be exposed to.

  10. Test Results Part 3 Structural: Drop Test • Two drop tests were performed • A few dents around the corners after the first test were found • A tear occurred after the second drop test on one of the sidewalls • The structure supported the maximum amount of weight allowed

  11. Structural: Kick Test • One kick test was performed • Minimal damage was done • The structure supported the maximum amount of weight allowed

  12. Structural: Whip Test • Two whip tests performed • No damage was found • The structure supported the maximum amount of weight allowed

  13. Structural: Test Conclusion • The three different structural tests performed show that our structure will withstand the ascent and descent of the flight with minimal damage

  14. Prediction

  15. Biggest Worries Hardware/Software -Geiger Counter Failure -Faulty Programing -Sensor Failure -Battery Life Data -Insufficient data -Inaccurate data -Inconsistent data

  16. Requirements Checklist
