HIGH ENERGY SOLID PROPELLANT COMBUSTION EFFICIENCY INVESTIGATION.
Abstract
The objective of this study, as related to the overall High Energy Solid Propellant Combustion Efficiency Program, is the development of an understanding of the combustion and performance of solid double-base propellants containing metal and metal-hydride fuels by a chemical and physical analysis of their particulate exhaust products. Thirty-four firings were conducted, using five pound subscale motors, in a closed underground 3400 cu ft tank. The propellants used were DDP (Aluminum), FHA (aluminum hydride), VCN and VCP beryllium, and VGB and VGC beryllium hydride. The exhaust and motor slag particulate samples were collected for each firing and analyzed chemically for free metal, metal oxide, carbide nitride, and physically for particle size spectrum. These data were correlated with parameters such as chamber pressure and temperature, expansion ratio, K, oxidation ratio, metal loading L and amount of slag remaining in the motor case. (Author)
