ALTITUDE TESTING OF THE J-2 ROCKET ENGINE IN PROPULSION ENGINE TEST CELL (J-4) (TESTS J4-1554-12 THROUGH J4-1554-19)

Abstract

Eight test periods involving a total of 14 starts of the J-2 rocket engine were conducted at pressure altitudes ranging from 93,000 to 111,000 ft. These tests were a continuation of an environmental verification and start transient investigation on a flight configuration J-2 engine (S/N J-2052). Firing durations ranged up to 50 sec; a total of 293.6 sec of engine operating time was accumulated during the test period. Unexpected excessive gas generator temperatures experienced on restart tests under simulated orbital restart conditions necessitated reorientation of the objectives for this test series. Satisfactory engine restart was subsequently obtained at turbine crossover duct conditions predicted for Saturn V (flight 501) restart with the propellant utilization valve in the full open position.
