HyperTEK is a modular, hybrid propellant rocket motor
system that uses readily available nitrous oxide (N2O)
and thermoplastic fuel grains. The HyperTEK system uses
the patented Kline valve to control the flow of oxidizer.
This unique design allows for safe, remote filling of
the oxidizer tank on the pad. Thousands of systems have
been in use around the world since it's design by eAc
in 1994. Designed primarily for use in launching small
experimental payloads by universities, colleges, research
institutes and sport rocketry enthusiasts, the system
is also intended to be a technology demonstrator for hybrid
propulsion technology. eAc has licensed the manufacturing
and distribution of the HyperTEK Hybrid Propulsion System
Technology Incorporated (CTI).
Extensive research and development by CTI and eAc has
refined the system yielding a high tech, low cost rocket
motor alternative to the current solid propellant rocket
motor. 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.
Incorporating the fuel, nozzle and motor case into one
injection molded component has eliminated the complicated
assembly of a reloadable system. 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.
