Two firings of the Rocketdyne J-2 rocket engine were conducted in Test Cell J-4 of the Large Rocket Facility. The firings were accomplished during test period J4-1801-03 at pressure altitudes of approximately 100,000 ft to evaluate S-IVB/S-V start condition effects on: (1) engine start transients, (2) gas generator outlet temperature, (3) augmented spark igniter operation, and (4) fuel pump low level stall margin for J-2 engine J-2052. Engine components were thermally conditioned to temperatures predicted for S-IVB/S-V first burn and one orbit restart on firings 03A and 03B, respectively.
