HTP (High-Temperature Photochemistry) Kinetics Measurements on Some Gun Propellant Combustion Reactions.
Abstract
Modeling of gun propellant combustion requires reliable input data on the kinetics of individual reactions involved. In this work the HTP (high-temperature photochemistry) technique is used to provide such data over wide temperature ranges. Detailed studies of the H + NH3 yields NH2 + H2 and H + N2O yields N2 + OH reactions have been made. In both systems quantum mechanical tunneling is found to contribute significantly to the overall reaction. For the latter reaction it is shown that a second channel leading to NH + NO contributes less than 7 percent below 2000 k. Keywords: Atomic hydrogen; Nitrogen oxides; Ammonia; Gun propellant reactions; High-temperature kinetics; Non-Arrhenius kinetics; Quantum-mechanical tunneling.
