    2. Rocket Flight Stability Rocket Flight Stability in Rocksim Thrust to weight motor selection in flight simulation

    3. Rail Exit Velocity Rocksim analysis, 6” Diam, 339oz loaded with K325, 10’ rail: Departure Vel=44.5 ft/sec Minimum vel for Stable flight=43ft/sec

    4. Parachute Sizes and Descent Rate Four parachutes: 1 36” drogue chute 1 36” nose cone chute 1 36” capsule chute 1 70” main chute

    5. Test Plans and Procedures Robot: Pilot practicing control via radio/video link Pitot tube: 220MPH leafblower test BP ejection test CO2 ejection test Flight video: trying to integrate into bay

    6. Scale Model Flight Test ˝ Scale model flew successfully, with Video! Rocket graveyard Lake Payload pod ejected successfully

    7. Dual Deployment of Avionics Test Dual Avionics Payload Aft: Black Powder Fore: Carbon dioxide (for low temperature, noncorrosive gasses on robot. Dual, redundant altimeters for maximum flight safety.

    8. Ejection Charge Amount Test-CO2 Forward Section Ejection Components of CO2-Rouse-Tech

    9. Ejection Charge Amount Test-BP Aft Section Black Powder Ejection Charge Body Dia. Squared =X1 X1 x Length of Open Body Dia. = X2 then… X2 x .006 = # grams of 4F Black Powder

    10. Nosecone Pitot payload Circuit integrated fully into nosecone ˝” Plywood Flange epoxied & screwed in nosecone 5 bolts hold bulkhead to flange Offset center for ease of reaching switches Hose from sensor to steel Pitot tube

    11. Nosecone Pitot circuit Same circuit as last year Tube to Hose to Sensor to Data Logger Data downloaded to Laptop PC, Excel Calibration via 220MPH blower

    12. Mission Commander Team Orion is honored to have a passenger! Gumby’s safety is mission critical Will have backpack parachute for safety Seat-belted into unused area in nosecone

    13. Altimeter Payload Bay All fiberglass for maximum strength Double-thickness bulkplates 2 x Ľ” threaded rods hold it together Two redundant altimeters (Missileworks and Ozark)

    14. Altimeter Bay Deployment Black powder for aft deployment, redundant, cartridges bolt to aft bulk plate CO2 for fore deployment, redundant, Rouse Tech., bolted to fore bulk plate Pyrodex combustion forces piston pin into CO2 cartridge

    15. SRV-1Robot- “Scorpio” Capsule First basic design of capsule First modified design of Capsule Final design of Capsule in airframe

    16. Payload Assembly All components of the capsule Robot’s G force frame support

    17. Payload Integration Feasibility Capsule in airframe Fitting the door

    18. Conclusion Team Orion’s project coming together!
