Gru and Vector

Gru and Vector are two mid-powered rockets that were designed, built, and launched with a gimbaled motor system in February 2024. The gimbaled motor involved changing the direction of exhaust flow by rotating the motor on two axes. This allowed both rockets to be actively controlled during flight. Each rocket had different parameters – Gru was longer and used a G12 motor, while Vector was shorter and used an F10 motor. These variations allow us to compare the effects of different motor burn times, thrust outputs, and rocket conditions on the functionality of the gimbaled motor. The components of the gimbaled system were designed and built in-house by students, primarily using 3D printing to manufacture components for various systems. Both rockets launched, and although sustained flight was not achieved due to low thrust-to-weight ratios, correction of attitude was seen during the flight.
