    The Propulsion sub-team of Charger Rocket Works is in charge of flight predictions, flight analysis, motor selection, and load path interfaces between the motor and rocket body. The team has created a 2 degrees of freedom flight prediction code to predict altitude, velocity acceleration, time to apogee, and micro-gravity time during flight. This code will be used to size to motor and predict the force requirements for load bearing bulk plates. The team is also in charge of the design of centering rings and load bearing bulk plates, as well as cooperation with the structure team for interfaces with the body of the booster. Below is a CAD of the motor tube used in the booster. The motor chosen for the competition is a J355.
