  1. TeamRocketLafayette College Flight Readiness Review

  2. Flight Analysis Intimidator 5: 5” diameter, 10’ length, 47 lbs • Motor: Aerotech L1300R • 4556 N-Sec of impulse • Predicted altitude • 5203’- RockSim • 5292’ - AeroDRAG • Altitude reached can be adjusted by adding or removing weight. • Rocket w/out additional weight: 44 lbs

  3. Flight Analysis • Thrust to weight ratio= 6.5:1 • Well above the suggested 5:1 • Launch Rail: • 12 ft high • Exit velocity - 65 ft/s - RockSim

  4. Flight Analysis • Parachute sizes • Drogue – 3 ft • Main – 12 ft • Parachute descent rates • Drogue: Must be between 50 and 100 ft/s • 87-90 ft/s– RockSim • 84.52 ft/s – Mathcad • Main: Must be between 17 and 22 ft/s • 21.1 ft/s– RockSim • 21.132 ft/s– Mathcad

  5. Rocket Flight Stability Static Stability Margin: 4.77 overstable

  6. Test Plans and Procedures (Overview) • Vacuum chamber testing of the R-DAS system and recovery altimeter completed • Full scale launch completed on March 19 • Ejection charge test completed March 18 • Static testing of full scale motor completed on March 18

  7. Test Plans and Procedures • Remaining tests: • Functional test of assembled payload bay • Verify all instrumentation in rocket (April 2) • Static tests: • Verify ejection charges • Vibration test • Second Full scale launch at METRA on April 2 (April 10 alternate date for MDRA)

  8. Full Scale Flight Test • Results • Two altimeter readings: 5123 ft and ~5380 ft • Predicted altitude from RockSim: 2806 ft • Predicted altitude from AeroDRAG: ~5800 ft • Predictions were 10% different from actual • First launch: completely successful • Second launch: partially successful recovery system

  9. Dual Deployment Avionics Test • Vacuum chamber used to re-verify deployment of drogue parachute at apogee and main parachute at predetermined height. • Drop in pressure causes altimeter to detect a change in “altitude”

  10. Static Test of Motor • Aerotech L1300R • S-load cell used • Results matched closely to expected values • Maximum thrusts of 290 lbs (static test) vs320 lbs (Aerotech) • Further calibration necessary

  11. Ejection Charge Amount Test • Ejection charge amount determined from Modern High Power Rocketry 2 by Mark Canepa • Drogue amount – 2.5 grams (redundant charge will be 3.75 grams) • Main amount – 7.5 grams (redundant charge will be 11.25 grams) • To verify that the charges will provide adequate force, the rocket was fully assembled with charges • Charges were ignited using a battery • Rocket successfully separated

  12. Payload Integration Feasibility • Payload bay acts as coupler for attaching body tubes • Dimensions sized with this in mind • Materials used will ensure integrity of bay • Pressure seal will guarantee accuracy of measurements

  13. Educational Engagement • 11 Local businesses were contacted • One possible sponsor • Local middle school students (48) built and launched small rockets • ‘A’ class motors was be used • Presentation on rocketry was be given • Lafayette hosts an afterschool program for underprivileged children • Water bottle rockets will be launched with them

  14. Educational Engagement
