Rocket Motor Launch
Name: Victor S, Gabriel V, Jenni Fuel: Straight Black Powder and Balcol Charcoal Core Diameter: End Burner and 1qt inch drill Rocket Motor: (I had trouble moving the images the test curve, but you can find it in the Motor Thrust Curve file) To get the thrust curve we put our video into adobe premier and counted each frame and lookedat the thrust in the monitor. Then to get more data about how our rocket works and how it would perform with a rocket, we had to calculate T and t. T or big T stands for Average Thrust, and t (little t) stands for burnout time in seconds. To calculate little t, or the burnout time all we had to do was take the number of frames and divide it by 30 since the frames were 1/30th of a second. To calculate average thrust we added up every measurement taken from every frame, added it up, then divided it by 30 because the frames were 1/30th of a second after we divided it by 30 we also divided it by 5.01 which was our t (burnout time in seconds) because as it's stated in the name that's how long it took for the engine to burn out completely. Reflection:This was a very cool project especially when we tested the motors. At first since I did not have a partner I was planning to go solo. But then Andrew tolled me that I needed a partner so he put me with Victor and Gabe. I did not find it difficult to work with them since I had worked on a project with them before. Also we wanted almost the same type of motor so we just put our ideas together and finished our design. For the motor test I was not able to be there, but I did see the video and the burnout time was a bit longer than I expected, but at least the motor did not explode.
