  1. Drexel RockSAT Launch Readiness Review • Kelly Collett • Christopher Elko • Danielle Jacobson • May 27, 2012

  2. LRR Presentation Contents • Section 1: Mission Overview • MissionStatement • Mission Objectives • Section 2: The Payload! • User’s Guide Compliance • Beta Prototype Testing • Section 3: Check-In Readiness • Plans for Integration • Documentation

  3. Mission Overview Drexel RockSat Team 2011-2012

  4. Mission Statement • Develop and test a system that will use piezoelectric materials to convert mechanical vibrational energy into electrical energy to trickle charge on-board power systems.

  5. Mission Overview • Demonstrate feasibility of power generation via piezoelectric effect under Terrier-Orion flight conditions • Determine optimal piezoelectric material for energy conversion in this application • Classify relationships between orientation of piezoelectric actuators and output voltage • Data will benefit future RockSAT and CubeSAT missions as a potential source of power

  6. Payload Design Drexel RockSat Team 2011-2012

  7. Design Overview Microcontroller G-switch Batteries Flight Decks Camera Standoff Supports Accelerometer Array Piezo Arrays

  8. Payload Design beta • Beta payload includes modifications to: • Camera housing • Organization of EPS components on top deck • Transistors and relays used to control power for EPS and VVS • Cantilever length: 3.0 in. Beta payload with wiring connections ready for vibration testing

  9. Physical Specs eurekasatpayload

  10. Electrical Design PEA I PEA II PEA III PEA IV Rectifier + Capacitor Rectifier + Capacitor Rectifier + Capacitor Rectifier + Capacitor Internal Memory Camera Arduino Microcontroller 3-AA Batteries Accelerometer I SD Card Memory Accelerometer II Legend Power connection Data connection Power (G-switch=1) 9V Battery 9V Battery G-Switch Wallops Latching Relay

  11. Updates Since FMSTR • Beta prototype complete and tested • VVS functioning • Switched to AA batteries, no regulator • Modified camera mounting bracket

  12. Testing Updates • Increased length of cantilevers • Lowered maximum output • Alpha: over 1 V for “diving board” • Beta: about 0.55 V

  13. Testing Updates

  14. Mission Requirements

  15. ARE YA READY KIDS?! ALMOST, CAPTAIN!

  16. Readiness • Ready! • Travel arrangements set • Payload is assembled and ready to go • Integration with Temple • Almost Ready! • Documentation • For Drexel Payload and Canister • Check-in Procedure

  17. Integration • Canister Sharing with Temple • Method of Integration: standoffs • Height: 9.07” • Combined Weight: 6.74 lb • Combined CG: x-1.32” y2.04” z2.10” • NOTE: material properties discrepancies • CG to be adjusted with systematic ballast placement • Procedure: tighten standoffs

  18. Complete Payload

  19. Complete Payload Temple Drexel

  20. Canister Integration ø 9.30” overall diameter 9.07” overall height 6.73 lbs. overall weight standoffs means of integration

  21. Action Items • Finish up documentation • Mostly drawings • Parts accounting • Tidying of documents • Ballasting, staking, etc. • To be completed after integration with Temple • Mostly at Wallops

  22. Check-In Inspections • Check-in procedure partially completed • So far so good

  23. Final Questions Drexel RockSat Team 2011-2012

  24. Questions • None right now! :D
