Abstract

Composite propellant combustion is studied experimentally with systematic variation of particle sizes and mix ratios of coarse and fine APs. Considering the different modes of oxidizer-fuel flames in heterogeneous systems, the complex flame model is described to identify what combustion mechanisms are important under what conditions. The effects of AP particle size, ratio of coarse to fine AP, and pressure on burning rates are discussed in terms of qualitative theory of flame microstructure.
