ALTITUDE DEVELOPMENTAL TESTING OF THE J-2 ROCKET ENGINE IN PROPULSION ENGINE TEST CELL (J-4) (TEST J4-1801-05)

Abstract

Twenty-one valve sequence operations of the Rocketdyne J-2 engine were conducted on August 15, 1967 in Propulsion Engine Test Cell (J-4) of the Large Rocket Facility, Arnold Engineering Development Center. The tests were accomplished during test period J4-1801-05 at local atmospheric pressure conditions to evaluate the effects of thermal conditioning on the main oxidizer valve operation. Fuel lead times of 1, 3, and 8 sec were simulated by varying the time between engine start and start tank discharge valve control solenoid energized. Engine components which were thermally conditioned included the (1) helium tank, (2) helium regulator, (3) main oxidizer valve closing control line, and (4) main oxidizer valve second stage actuator.
