This report summarizes the studies of ingredient decomposition and sandwich burning during the period October 1985 to September 1988. A CO2 laser pyrolysis facility was built and preliminary tests on propellant ingredients were conducted. Results showed presence of a liquid state or reacting froth on the surface of all ingredients tested AP, AN, PBAN, NMMO and BAMO-THF. Ingredient combustion behavior was studied by the edge burning sandwich method using sandwiches of AP with PBAN, NMMO and BAMO-THF. The effects of Fe203, Fe204 and catocene 10 level in the binder lamina were evaluated. Burning with BAMO- THF was qualitatively similar to that with PBAN, with the correspondingly high burning rate. Combustion, Solid propellant.
