Three firings of the Rocketdyne J-2 rocket engine S/N J-2047 were conducted in Test Cell J-4 of the Large Rocket Facility. The firings were accomplished during test periods J4-1801-11 and -12 at pressure altitudes ranging from 98,000 to 104,000 ft at engine start. The objectives of these tests were to (1) evaluate the effect of altitude environment on engine operation by a comparison of Rocketdyne sea-level acceptance test (624061) data with AEDC altitude test data and (2) evaluate engine transient operation with conditions simulating an S-IVB/S-V two orbit restart and compare results with engine J-2052 data for similar conditions.
