Rocket propulsion system elements may perform differently in the low pressure of the space environment than during sea level firings and it is imperative that the behavior of the propulsion system in space be known prior to its use in space missions. These research firings were conducted to prove this research motor will start and stop on command in the space environment using igniters of a new design. VTC 1-42B which is evacuated by a steam-driven, 2-stage, ejector-diffuser system was used to simulate pressure altitudes up to 120,000 feet. Two firings of this motor (AMV7B) were performed because on the first firing the igniter failed to function as intended and the second test was required to obtain added information on reliability of this component. All components of the Vertical Test Facility performed satisfactorily, which resulted in simulated altitudes above 100,000 feet during the firing of the rocket motor. (Author)
