MIT Rocket Team: P9100 Motor Test

What a way to start the year! MIT Rocket Team have certainly set the mark for others to follow with the test of their new P motor. Yielding a 15 % performance increase from last year’s tests, delivering a peak thrust of 12,632 N, specific impulse of 74,042 Ns over a burn time of 8 seconds. The motor is intended to power the team’s Hermes II rocket to ~86,000 ft, which will serve as the first stage for a space shot attempt in 2020.

The new propellant formula burned slower, and with better specific impulse. All combined, our various improvements yielded 15% higher performance than last year. We are preparing to fly this motor in March.
