GPSFlight in nose cone Variable Drag Configuration (VDC) Four-fin design Avionics Featherweight Raven-2 PerfectFlight MAWD Dual deployment 14
Center of Pressure: 90.25” Center of Gravity: 75.23” Over-Stable 15
AEROTECH L1500T Total Impulse:5120 Ns Casing: 98/5120 Average Thrust: 330 lbs Peak Thrust: 380 lbs Burn Time: ~3.5 sec Thrust to weight: ~6.7 16
Drag force is linear to ~30 degrees Approximate altitude loss ~1.2%/degree 30 degree deployment yields ~36% loss Must yield max altitude below 7180 ft and above 5280 ft 17
