Burning rate data determined over twenty years ago at the Ballistic Research Laboratory BRL and disseminated to only a limited audience have been referenced in several recent reports. This report provides a complete compilation of the experiments, the data, and the analyses to provide a usable reference for current investigations. It compares strand burner and closed chamber rates for the same propellant. Standard army gun propellants M1, M2, M5, M6, M8, M10, and M17 were re-extruded into 3mm 18 in. and 6mm 14 in. strands for strand burner tests at pressures of 3.4 to 310 MPa 500 to 45,000 psi and in closed chamber tests at densities of loading delta of 0.089, 0. 174, and 0.258 gcc. Fifteen additional lots of standard propellants were tested in the closed chamber at densities of loading of 0.084 and 0.140 gcc. The report presents the raw data, method of calculation for burning rate, and coefficients for various burning rate equations. The report also proposes an empirical relationship between the propellant flame temperature, and the burning rate parameters.
