BYU Propulsion Development – Experimental LOX/Paraffin Hybrid Rocket [PDF]

open access: yes, 2022
The "Blue Jay" is a 12 ft., LOX and paraffin hybrid rocket with a designed total impulse of 20,330 Ns. The rocket will have its maiden flight summer 2022 at the Friends of Amateur Rocketry with a target altitude of 10,000 ft. above ground level. The rocket is expected to weigh around 100 lbs. dry. This is BYU's first hybrid rocket, and one of the first
