Nine firings of the J-2 rocket engine are reported. The firings were accomplished at pressure altitudes ranging from 95,000 to 112,000 ft at engine start. The objectives of these tests were to investigate S-II/S-V start condition effects on engine start, gas generator ignition characteristics, and fuel pump operation. Engine thermal condition extremes for S-II flight configuration were duplicated. Satisfactory engine operation was obtained. Accumulated firing duration was 111.6 sec.
