LOX/Hydrocarbon auxiliary propulsion for the Space Shuttle OrbiterThe initial efforts are reported of a study evaluating liquid oxygen/hydrocarbon (LOX/HC) auxiliary propulsion system (APS) concepts for a second generation Space Shuttle Orbiter. The APS consists of: (1) an orbital maneuvering subsystem (OMS), (2) an aft reaction control subsystem (ARCS), and (3) a forward reaction control subsystem (FRCS). The overall study approach compares candidate LOX/HC concepts and evaluates major system/component design options, regarding the overall system, pressurization assembly, propellant tankage and feedline, accumulator, and engine conditioner and thrust chamber assemblies. Among the HC fuels considered are C3H8, CH4, NH3, and C2H5OH.
