T1: Rocket Science To extend our reach to the stars above! Video
Introduction • Goals: • Predict apogees • Rocket equation • Simulation • Build/Test Rockets • Different models, masses, engines, etc. • Analyze/compare results • Apogee vs. mass • Acceleration vs. mass • Apogee vs. engine type
cg Forces On A Rocket weight cp lift drag thrust
Rocket Equations Newton’s Second Law Tsiolkovsky Our Theory
Simulation OpenRocket—Sampo Niskanen
Launch: Measurements Angle Gun Timers Video Analysis Altimeter
Experimental Problems • Malfunctioning batteries • Shock-cord snap • Rocket explosion • Nose cone explosion during descent • Rocket with altimeter stuck in tree for 4 days
Analysis: Mass vs. Apogee Results show Our rockets Can fly Kind of high Exemplifying a negative and nonlinear Trend
Conclusion Mass vs. apogee → exponential, negative Engine vs. apogee → logarithmic, positive Mass vs. acceleration → cubic polynomial To optimize model rocket flight, rocket mass must be minimized while still maintaining the center of gravity above the center of pressure. Additionally, upgrading the engine class makes the rocket go higher. These graphs present the optimal conditions for highest apogees.
