Solid Propellant Kinetics. 3. Experimental Study of the Opposed Flow Solid Propellant Diffusion Flame

Abstract

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 AP/CC 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.
