    Description: The generation of technology for injectors, cooled thrust chambers, valves, and ignition systems is discussed. The thrusters are designed to meet a unique and stringent set of requirements, including: long life for 100 mission reuses, high performance, light weight, ability to provide long duration firings as well as small impulse bits, ability to operate over wide ranges of propellant inlet conditions and to withstand reentry heating. The program has included evaluation of thrusters designed for ambient temperature and cold gaseous propellants at the vehicle interface.

    Description: The development of an injector/thruster concept capable of pulsing a liquid hydrogen/liquid oxygen attitude control propulsion system thruster over thrust and chamber-pressure ranges of 625 to 1250 lbF and 250 to 500 psia, respectively, is discussed. It is shown how continuing search for a simple light-weight, high-performance reaction control system concept led to successful operation tests at cryogenic propellant temperatures (150 and 45 degrees Rankine for oxygen and hydrogen, respectively). The analytical and experimental phases of the liquid/liquid thruster technology efforts are examined.

    Description: Successful operation of a pulsing liquid hydrogen/liquid oxygen attitude control propulsion system thruster (1250 lb sub f) at cryogenic inlet conditions while maintaining high specific impulse and low impulse bit capability was demonstrated. Significant technical advances and departures from conventional injector design practices were necessary in order to achieve an operable thruster. These advancements were achieved through extensive analyses of heat transfer and injector manifold priming that established the baseline feasibility for an actual hardware design. The primary subject of this paper is the result of experimental evaluation of the 45 R hydrogen inlet temperature injector concept. The test matrix consisted of 66 hot firing tests in a heat sink thrust chamber.

    Description: A comprehensive program has provided the technology groundwork for the use of hydrogen-oxygen propellants in the Space Shuttle Attitude Control Propulsion System (ACPS) thrustors. This work has concentrated on generation of technology for injectors, cooled thrust chambers, valves, and ignition systems. The thrustors are designed to meet a unique and stringent set of requirements, including: long life for 100 mission reuses, high performance, light weight, ability to provide long duration firings as well as small impulse bits, ability to operate over wide ranges of propellant inlet conditions and to withstand reentry heating. The program has included evaluation of thrustors designed for ambient temperature and cold gaseous propellants at the vehicle interface.
