Abstract : To examine the gas-kinetics parameters pertinent to the flame reactions of ammonium perchlorate (AP) based propellants the authors employed the heterogeneous opposed flow diffusion flame. In this combustion system a diffusion flame is formed in the stagnation region between a gaseous stream of fuel and an opposing stream of oxidizer originating at the solid surface of AP. With increasing fuel flux the steady-state mass flux of AP reaches a value at which the kinetics of reaction limit the consumption of reactants. Both the composition of the solid oxidizer and the gaseous fuel were varied in the experimental studies. The effects of different catalysts and solid fuels were examined on the burning rate characteristics of the solid phase. A number of gaseous hydrocarbon fuels were used. Based on the results kinetic expressions are derived for the overall combustion progress in the diffusion flame of solid propellants based on AP. (Modified author abstract)
