Altitude Developmental Testing of the J-2S Rocket Engine in Propulsion Engine Test Cell (J-4) (Tests J4-1902-01 Through J4-1902-04)

Abstract

Five firings of the Rocketdyne J-2S rocket engine were conducted in Test Cell J-4 of the Large Rocket Facility between December 5, 1968, and January 10, 1969. These firings were accomplished during test periods J4-1902-01 through J4-1902-04 at pressure altitudes of approximately 100,000 ft at engine start to investigate engine idle-mode operation, transition from idle mode to main stage, and steady-state operation at main stage. The engine started successfully in all cases and two planned transitions from idle mode to main stage were accomplished. The thrust chamber and injector were damaged extensively during a 288.5-sec duration idle-mode firing (04A).
