Abstract:

This report is divided into three parts. The first part gives the strand burning rates of the various propellants used in the combustion instability studies, compares the results with the granular diffusion flame theory, and points out the need for a more thorough examination of the burning-rate-pressure relationship assumed for the mathematical models of combustion instability. The second part presents additional experimental data on nonacoustic instability for propellants using a carboxy-terminated polybutadiene binder these data like those obtained from polyurethane binder propellants also deviate from the one-dimensional theory. The third part of the report presents an extended mathematical description of nonisentropic behavior in the T-burner and compares experimental observations of the gas motion and temperature with theoretical predictions.
