DEVELOPMENT OF LOW TEMPERATURE GAS GENERATOR TECHNOLOGY.

Abstract

The objective of this program is to characterize hydrazine-based monopropellants which, by the use of ammonia and ammonia-water diluents, re capable of producing clean, low temperature gases when passed through a catalytic decomposition chamber. During this report period sixteen gas generator firings were conducted for the purpose of establishing the operating characteristics of various hydrazine propellants containing either ammonia or ammonia and water diluents. The propellants, containing up to 60 percent by weight NH3 operated very well in the gas generator which uses the Shell 405 catalyst. Exhaust gas temperatures in the range of 550 F to 1200 F were measured. Materials compatibility tests have been initiated with six different propellants and five different metals in both the welded and unwelded condition. Preliminary results indicate that neither type 1100 nor 6061-T6 Aluminum are compatible with hydrazine-water propellants. (Author)
