Abstract:

Five firings of the Rocketdyne J-2 rocket engine SN J-2047 were conducted in Test Cell J-4 of the Large Rocket Facility. These firings were accomplished during test period J4-1801-16 at pressure altitudes of approximately 100,000 ft at engine start to investigate S-IIS-V 1 fuel pump operation during the start transient at lower than minimum model specification inlet pressure, 2 thrust chamber pressure buildup rate with low starting energy, and 3 gas generator and augmented spark igniter temperature transients with warmest and coldest expected thrust chamber temperatures as predicted from the AS-501 countdown demonstration. Engine operation was satisfactory for all firings. The accumulated firing duration was 46.2 sec.
