Evaluation of Various Effective Parameters on the Burning Rate of Composite Solid Propellants

Investigation shows that the some complex and expanded parameters are effective on the burning rate. In this paper we evaluate the effect of particles dispersion, size of AP particle, the size of Al particles, Fe2O3, viscosity, shape factor, the size of mixer and the mechanical parameters such as tensile and stress on the burning rate. These studies show that the decrease of AP particles, size distribution, using nano-size Al particles, decreasing the mixer size and adding burning rate catalysts such as Fe2O3 can increase the burning rate of composite propellant. Also loaded stress and strain can increase this parameter.
