Apollo Block II SPS Engine (AJ10-137) Mod I-D and Mod I-E Bipropellant Valves Qualification Tests (Phase 6, Part 3)

Abstract

Simulated altitude testing of the Apollo SPS Block II engine was conducted to qualify the latest design bipropellant valves (Mod I-D and Mod I-E) , to investigate combustion overpressure during ignition, and to determine the heating rates of the flight-type electric heaters on the propellant lines and bipropellant valve. Propellants used were nitrogen tetroxide and 50/50 hydrazine/unsymmetrical dimethylhydrazine. Fifty-one test firings were made for a total of 922 sec of firing time during four test periods.
