Abstract:

The decomposition of many solid reactants during combustion leads to the formation of gaseous hydrocarbons and oxides of nitrogen which can react to support a flame above the surface of the solid. These flames can provide heat which is fed back to the propellant surface and thereby influence the burning rate of the solid. In the case of nitramine based solid rocket propellants, the gas phase decomposition products include significant amounts of Formaldehyde. Nitrogen dioxide, Hydrogen Cyanide, Nitric oxide, Nitrous oxide, oxygen. This study is intended to provide experimental data on the structure of hydrocarbon flames supported by oxides of nitrogen in order to establish the reaction mechanism for such flames. Laminar, premixed, flat flames of methaneNO2O2 and CH2ONO2O2 have been investigated and a reaction mechanism is suggested which accounts for all of the major observations in the data.
