Abstract:
The details of the chemical processes which occur during propellant combustion are generally not known, yet, they directly affect such important propellant combustion characteristics as ignition and burn rate. Recently, a collaboration has been set up to study these details in a coordinated and comprehensive way. This study is concentrating on nitramine-based propellants since their ignition and burn rate properties are of great current interest and importance. This report presents initial results of a long-term study in which both theoretical and experimental efforts are being pursued. Major results in theory include the calculation of thermochemical properties of a number of nitramine decomposition products and combustion intermediates, as well as specifying pathways for the formation of the reactive species HCN, H2CO, NO2 and N2O. Also, quantum chemical models for the interaction of nitrogen-type oxidizers with H atoms have been developed. Keywords: Propellant combustion, Nitramines, Cyanogen flames, Nitrogen dioxide flames.
