  4. Mission Statement • Design, build, test and fly a hybrid rocket • Achieve an altitude of exactly 1.00 mile • Measure gamma radiation as a function of altitude • Measure temperature and pressure • Measure x-, y-, z- acceleration during flight • Done safely with no injuries, no damage to property • Rocket recovered without damage

  5. Airframe Length 90.3 inches 7.5 feet Diameter 4.0 inches Span Diameter 12.0 inches Estimated Mass 246.4 ounces15.4 pounds

  6. Airframe Center of Pressure 65.5 in Center of Gravity 52.0 in Margin of Stability3.40 body calibers over stable

  7. AirframeScale Model Test • Test planned for middle of February

  8. Motor Contrail Rockets Certified K-888-BM Hybrid Motor Diameter of motor 75 mm Length of Motor 40.0 inches Nozzle medium Fuel Grain Used Black Smokey

  13. Payload • Science payload consists of: • Flight computer number 1 • Flight computer number 2 • Embedded microcomputer system • Radiation counter • Temperature sensor • Pressure sensor • x-, y-, z- accelerometers • Battery power supply

  14. Payload • Science instruments, flight computers, recovery transmitter and batteries fit inside 3.78 in diameter by 12.0 inch long phenolic coupler tube • Switches ,status LEDs, computer connectors mounted on ring in the middle of the coupler

  15. Payload Side profile of science payload with circuit boards and batteries mounted

  17. Payload Geiger counter and x-, y- accelerometers on right Z- accelerometer in middle Embedded controller, temperature and pressure sensors on right

  18. Payload • Science Payload Objectives. • Test and calibrate a Geiger-Mueller radiation counter • Interface Geiger counter to embedded controller to operate the instrument and collect and store the data. • Test the complete instrument mounted in the airframe using laboratory alpha, beta and gamma radiation sources. • Test and calibrate pressure sensor • Test and calibrate a temperature sensor • Test and calibrate a low sensitivity and a high sensitivity 3-axis accelerometer

  19. Payload • State the payload success criteria Payload success will be achieved if all the sensors perform satisfactorily and data from each is collected and stored in the on-board computer memory.

  20. Avionics The recovery subsystem is composed of the following components: • PerfectFlite MiniAlt/WD to measure and store altitude and deploy drogue and main parachutes. • DT2x Data Transfer Kit for connecting MiniAlt/WD to computer • G-Wiz MC-2.0 Flight Computer to provide redundant backup of the PerfectFlite • Nine pin female to female cable with subminiature D connectors to connect G-Wiz MC-2.0 to computer

  21. Avionics • Software to download data from G-Wiz • Ejection charges with electric matches to deploy parachutes • SkyAngle Main Parachute with 57 square feet • SkyAngle Drogue Parachute with 6.3 square feet • Shock cord – to be determined • Walston Retrieval System with Rocket Transmitter, 3-Channel Receiver, and 3-element Antenna

  22. AvionicsDual Deployment Avionics Test • Test planned for middle of February PerfectFlite MiniAlt/WD Official USLI Altimeter and Flight Computer

  23. Avionics G-WIZ MC-2 Backup Altimeter and Flight Computer

  24. Launch Operations • We plan to assemble the motor ahead of time, so that all we have to do is load the nitrous • Draft Launch Plan in Appendix A in CDR, Page 29

  25. RecoveryEjection Charge Amount Test • Test planned for middle of February • Walston Retrieval System for Rocket Locating • SkyAngle 24 in for Drogue • SkyAngle Large Cert-3 for Main

  26. Outreach The timeline with major milestones is on page 5 • The milestones accomplished are grayed out in the table • We are behind in launching scale model rocket • We are slightly behind in the construction of the airframe • We are behind in writing procedures needed • We are behind in outreach with the Girl and Boy Scout Programs.

  27. Outreach We are excited about a rocket display in the Harding University Library in late February We have applied to be introduced with a program in Harding University Chapel that could potentially reach more than 5000 students We will be giving talks and posters on the USLI Program at Arkansas Undergraduate Research Conference and Sigma Xi Poster

  28. Outreach Funds have been obtained to do an excellent job on this project. We acknowledge the Arkansas Space Grant Consortium for funding all 4 years of participation
