Thrust E80 Static Motor Test Spring 2009
Forces on a Rocket
The Question In the event of a crash landing of your rocket, what will be the effect on the instruments inside the rocket? (Translation) What is the velocity of impact? What is the impulse response of the rocket structure?
Isentropic Flow through Nozzles For subsonic flow (Ma<1) For supersonic flow (Ma>1) For sonic flow (Ma=1)
Isentropic Flow of Perfect Gas Through Converging-Diverging Nozzle
Rocket thrust summary
E80 Static Motor Test Lab 1.Calibrate Load Cell 2.Measure Thrust Curve of Rocket Motor 3.Measure Average Mass Flow Rate 4.Compute combustion pressure assuming isentropic nozzle flow. Model burn rate of rocket fuel. 5.Estimate the impact velocity of your rocket.
