Project Goal

Phoenix Propulsion Program (PPP) was formed to research, develop, and realize the Green Phoenix experimental hybrid rocket motor. Green Phoenix gets its "Green" name from the use of biofuels as well as a design emphasis on reusability. Green Phoenix is the first of its kind; the engine combines RISE's novel biofuel mixture with a cost-effective, powerful nitrous oxide-based oxidizer to produce thrust.

A series of valves and ignition equipment allows Phoenix to throttle deeply and restart mid-flight, which is necessary to complete Alpha's complex landing maneuvers.
