Four firings of the J-2 rocket engine were conducted in Test Cell J-4 of the Large Rocket Facility. The firings were accomplished during test period J4-1801-08 at pressure altitudes ranging from 92,500 to 107,000 ft at engine start. The objectives of the test were 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 high level stall margin for J-2 engine S/N J-2052. The accumulated firing duration was 70.32 sec. Satisfactory engine operation was obtained.
