The kinetics of high-temperature reactions associated with solid- propellant deflagration are studied quantitatively by means of the heterogeneous opposed flow diffusion flame. In these experiments a cylindrical gas jet containing the gaseous fuel impinges on the surface of a solid propellant composed of ammonium perchlorate AP and copper chromite CC catalyst. A diffusion flame is established in the stagnation region formed by the two opposed flows of reactants. With increasing mass flux of gaseous fuel, the mass flux of solid APCC grows until a limiting condition is reached governed by the kinetics of reaction. Further enhancement in fuel flow does not result in any increase in the mass consumption rate of solid oxidizer.
