Six firings of the Rocketdyne J-2 rocket engine were conducted in Test Cell J-4 of the Large Rocket Facility. This testing was in support of the J-2 engine application on the Saturn IB vehicle. The primary objective of this test period was to evaluate engine start transients with the engine orificed for an uprated thrust level of 240,000 lbf at a 5.5 mixture ratio. The engine was orificed for performance significantly in excess of the target level, and in fact for a value which could not be attained without exceeding safe operation limits. However, engine start transients were satisfactory with the propellant utilization valve in the open position. The total accumulated firing duration for the six firings was 63.9 sec.
