Kinetics of Propellant Combustion and Muzzle Flash Reactions
Abstract
Kinetic measurements are reported for elementary reactions important to the understanding and modeling of gun propellant combustion. The high- temperature photochemistry (HTP) technique, which allows measurements in the 300 to 1800 K range on isolated elementary reactions, is principally used to generate this information. The following are the recommended rate coefficients, in cc/molecule/sec, H + NH(3) yields NH(2) + H(2), k(490-1780K) = 9.0x10(-19)(T/ K)(2.40)exp(-4991 K/T), D + ND(3) yields ND(2) + D(2), k(590-1220K) = 3.2x10(- 10)exp(-8810 K/T), H + N(2)O yields N(2) + OH, k(410-1230K) = 4.2x10(-14)exp(- 2290 K/T)+3.7x10(-10)exp(-6920 K/T), D + N(2)O yields N(2) + OD k(450-1210K) = 3.5x10(-13)exp(-3600 K/T) + 5.3x10(-10)exp(-9170 K/T), H + NO(2) yields OH + NO k(296-760K) = 2.2x10(-10)exp(-182 K/T), and H + CH(3)NO(2) k(360-570K) = 1. 0x10(-11)exp(-1981 K/T). The reactions are discussed in terms of transition state theory, with tunneling where appropriate. Potential alternate reaction mechanisms and the combustion conditions under which they could occur are considered.
