Abstract:

Fourteen firings of the Rocketdyne J-2S rocket engine SN J-115 were conducted during test periods J4-1001-16 through -20 between March 10 and May 19, 1970. The major objectives of these tests were 1 development of a throttling capability using a variable-position tapoff valve for thrust control 2 demonstration of satisfactory idle-mode operation both pre- and post-main stage over a wide range of fuel and oxidizer pump inlet pressures 3 determine the suitability of the S-IVB propellant recirculation system to prefire condition propellants and prechill engine propellant pumps and 4 determine steady-state engine performance during main-stage operation. All major objectives were satisfactorily accomplished.
