For Technical Information Click Here HyperTEK - Hybrid Rocket Propulsion System HyperTEK is a modular, hybrid propellant rocket motor system that uses readily available nitrous oxide (N2O) and thermoplastic fuel grains. Designed primarily for use in launching small experimental payloads by universities, colleges, research institutes and sport rocketry enthusiasts. Hybrid motors have several safety advantages over solids. The fuel and oxidizer are isolated from each other until just before ignition, thus eliminating the requirement for a low explosive permit during transportation and storage of rocket motors. The HyperTEK hybrid propulsion system uses a remote fill/fire launch system as well as 100% pyrotechnic free ignition system The HyperTEK flight motor consists of three major parts: the oxidizer tank, the injector bell and the fuel grain. The fuel grain is molded from thermoplastic and has an insert-molded silica/phenolic nozzle. This monolithic grain functions as both the fuel and the combustion chamber. Complicated assembly of a reloadable system has been eliminated by incorporating the fuel, nozzle and motor case into one injection molded component. The fuel grain simply screws onto the injector bell prior to flight and the spent fuel grain is unscrewed and discarded of after each flight. The injector bell has field interchangeable injector orifices for tailoring the time/thrust profile to the needs of the rocket. Potential applications include small sounding rockets, RATO boosters and more.
