Burning Rates of Standard Army Propellants in Strand Burner and Closed Chamber Tests
Abstract
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 (1/8 in.) and 6mm (1/4 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 g/cc. Fifteen additional lots of standard propellants were tested in the closed chamber at densities of loading of 0.084 and 0.140 g/cc. 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.
