YJ-1S – Liquid Fuel Rocket Engine

We’ve seen Teensy boards in rockets, satellites, and more, but the first step of getting space-bound is developing a reliable engine.

Georgia Tech’s student-run Yellow Jacket Space Program enlisted three proud Teensy 3.6s in their mission to develop a liquid oxygen/kerosene rocket engine, the YJ-1S.

The first Teensy is used as a switchboard to control individual valves within the engine, as well as initiate engine startup and firing sequences. The engine controller uses another two Teensy boards to communicate with the switchboard and take control of the engine valves once initiated.

The results in the video below speak for themselves, and demonstrate the engine meeting its 790 pounds of force thrust target.
