An Investigation of Preferential Interfacial Reactions in Nonmetalized Composite Solid Propellant Combustion

Abstract

Four nonmetalized solid propellants were burned at 500psi in strands of 1/2 in. by 1/2 in. cross section and 2 in. length in both a dewetted and an as-cast state. Strands were burned at acceleration levels from zero to 1000g normal and into the burning surface, and 50g and 1000g normal and out of the burning surface. The effects of changing interfacial characteristics of the oxidizers and binder by prestressing (dewetting) were studied to determine if preferential interfacial reactions between binder and oxidizer particles provided an accurate explanation of burning rate augmentation.
