DEVELOPMENT OF LOW TEMPERATURE GAS GENERATOR TECHNOLOGY.
Abstract
The objective of this program was to characterize hydrazine-based monopropellants that, by the use of ammonia and ammonia-water diluents, are capable of producing clean, low-temperature gases when passed through a catalytic decomposition chamber. A series of 21 reactor tests were performed to establish the concentration limits for satisfactory reactor operation. The minimum hydrazine content for reliable operation was found to be 45 percent for hydrazine diluted with water, 42.5 percent for hydrazine diluted with both ammonia and water, and 40 percent for hydrazine diluted with ammonia. Six propellant compositions were selected and were characterized by a series of 22 reactor firings and by physical property measurements. Materials compatibility tests were performed at 120 degrees F for six propellant compositions with selected samples of aluminum, stainless steel, and titanium, as well as welded samples. (Author)
