| الملخص: | Title screen This study presents a mathematical model and a calculation method of the nonstationary combustion rate of metalized solid propellant (nitroglycerin powder with aluminum particle additives) under blowing conditions. The combustion of metalized fuel flat surface under unlimited blowing flow is investigated. The mathematical model describes the erosion effects of solid fuel through boundary layer approximation. The blowing effect is considered in turbulent heat-mass transfer. Results of theoretical and numerical analyses show the influence of aluminum powder additives on the burning rate of solid propellant under blowing flow. This study provides data on the dependence of propellant burning rate on blowing flow speed and dispersion of metal particles in the solid propellant.
