Combustion of Nitramine and Nitrate Ester Propellants
Abstract
The burning rate of some nitramine and nitrate ester propellants has been measured as a function of the ambient gas composition and pressure. The presence of oxygen is most strongly felt at low pressures where further oxidation of the combustion gas enhances the burning rate by increasing heat release. However, at higher pressures, the burning rate is unaffected by oxygen. The overall flame chemistry has been found to follow 2nd- and 3rd-order rates for the nitrate ester and nitramine propellants, respectively. Emissions by carbon and CN from the combustions indicate that all these flames are fuel-rich with a predominantly RCN-type fuel. A number of flame reactions, with and without oxygen, have been considered to explain the spectra and the burning behavior of the propellants.
