1. ARLISS Presentation September 18, 2009 Bruno’s Country Club HoloMua, “Moving Forward” Premo Ames II – Electronics & Project Manager JoleenIwaniec – Programmer Todd Esposito – Airframe Development MakanaCiotti – Airframe Construction

3. “HoloMua”Moving Forward The Continuing Efforts at Windward Community College

4. Sponsors • Hawaii Space Grant Consortium • AeroPac • Center for Aerospace Education

5. ARLISS • A • Rocket • Launch for • International • Student • Satellites • Simulated Satellite recording data simultaneously navigating it self to a predetermined location on earth autonomously.

6. SUAVSmall Unmanned Aerial Vehicle • Advantages vs. Ground Traverse Vehicle • Higher return velocity • Requires less power • Has a better chance against a headwind • Obstacles to be overcome • Autonomous flight control • Navigation in 3D vs. 2D • The intricacies of aerodynamics • HALO (High Altitude Low Opening)

7. Descent Phases • Rapid Descent Phase • Take initial heading • Begin steering toward the target • Release parasail at 1100 ft. • Parasail Descent Phase • Continue steering towards target via parasail

8. Descent Phases

9. 2008 ARLISS Results • 1st launch – Failure • Module failed to eject from carrier • 2nd launch – Failure • Module failed to eject from carrier

10. Cause of Failure • Module built to previous carrier specifications. • Carrier unable to seal properly • HCX Flight computer confused at apogee event sending carrier back into rocket

11. New Direction • New Air Frame Design • Built to current carrier specifications • 25% volume increase for electronics • Parafoil chamber volume increase • Improved Electronics • Isolated electronic systems • Easier programing

12. 2009 Air Frame Design

13. 2009 Air FrameProto Design Testing • Mock Prototype design used for testing flight characteristics. Larger scale model under construction for future testing

14. 2009 Module

15. Electronic Systems • Navigation and Steering • Parallax Propeller Micro Controller • Parallax GPS Module • Parallax Servo Motor • Utilized Spin program

16. Electronic Systems • Data Collection Unit 1 (PB2) • Parallax BS2P Micro Controller • Parallax DS1620 Temperature Sensor • Parallax GPS Module • Parallax EEPROM

17. Electronic Systems • G-Wiz HCX Flight Computer • Parasail Release • Data Collection • Acceleration • Altitude • Pressure • Speed

18. GPS Navigation • Orientation relative to the target determined via GPS signal uses the angle of the craft’s position relative to the target to determine whether to turn or not • greater than a certain degree – right turn • Less than a certain degree – left turn

19. 2009 ARLISS Results • 1st launch – Successful Deployment • 0.6 miles from target • 2nd launch – Successful Deployment • 2.0 miles from target

20. 1st Launch Details • Low Risk Flight • High winds non-existent • Module deployment with parasail deployed upon exit from carrier • GPS data from PB2 (passenger board – data collection) corrupt. **possible cause – weak GPS signal** • Navigation appears to be working – module found heading towards target, while rocket parts found further away.

21. 2nd Launch Details • Low Risk Flight • High winds non-existent • Module deployment with parasail deployed upon exit from carrier • Moved GPS sensor for PB2 out of module for increased GPS sensitivity • Module parasail shroud lines found tangled – module could not steer

22. 2nd Launch Data
