  12. The Alpha

  13. Launch: Trajectory

  14. Launch: Measurements Angle Gun Timers Video Analysis Altimeter

  15. Experimental Problems • Malfunctioning batteries • Shock-cord snap • Rocket explosion • Nose cone explosion during descent • Rocket with altimeter stuck in tree for 4 days

  16. Data: Simulation

  17. Data: Mass vs. Apogee

  18. Analysis: Mass vs. Apogee Results show Our rockets Can fly Kind of high Exemplifying a negative and nonlinear   Trend

  19. Data: Mass Vs. Acceleration Video

  20. Data: Mass Vs. Acceleration

  21. Data: Engine Type vs. Apogee

  22. 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.
