Five test periods which included 16 starts of the Rocketdyne J-2 Rocket Engine were conducted at pressure altitudes from 95,000 to 108,000 ft in Test Cell J-4. The tests were Saturn S-V/S-II start transient investigations using a flight configuration J-2 engine and S-IVB battleship stage. Firing durations were programmed for 5 or 30 sec, and the accumulated firing time was 206.1 sec. These tests completed the first series of full-scale S-V/S-II start transient investigation testing to be conducted at pressure altitudes in excess of 95,000 ft. (Author)
