Altitude Developmental Testing of the J-2S Rocket Engine in Rocket Development Test Cell J-4 (Tests J4-1001-16 through -20)
Abstract
Fourteen firings of the Rocketdyne J-2S rocket engine (S/N 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.
