Hybrid Rocket Motor Design Project. One of the main components of this course was the semester design project in which each student team designed, built and tested a 5 lbf thrust hybrid rocket motor. The thrust chambers were fabricated from aluminum and the nozzles were fabricated from graphite. Solid fuel grains consisting of HTPB and HTPB/Al were produced by each team. The oxidizer was gaseous oxygen supplied at 500 SLPM. The chamber pressure was constrained to 100 psig. Each rocket was tested on a thrust stand that enabled the measurement of instanteous oxygen mass flow rate, chamber pressure and thrust. With these data, each team was able to measure specific impulse (Isp), characteristic exhaust velocity (C*), thrust coefficient (Cf) and compare these measurements to their theoretical models, which predicted instaneous O/F, C*, Pc, and thrust.
This website contains pictures, movies and test data from each of the rockets. Enjoy!
Here is a power point presentation that describes the project and development of the thrust stand.
