Abstract:

Ten idle-mode firings of the J-2S rocket engine SN J-112 were conducted during test periods J4-1001-08 through J4-1001-10, and J4-1001-12 through J4-1001-14 between September 2 and October 15, 1969, in Rocket Development Test Cell J-4 of the Engine Test Facility. The primary objectives of these firings were to determine engine idle-mode operating characteristics at various engine mixture ratios utilizing a new noncompartmented injector. Engine performance, as indicated by characteristic velocity, was 120 percent higher than experienced with previous compartmented injector designs at nominal pump inlet conditions. Total accumulated engine idle-mode operation was 1408.2 sec.
