This paper proposes a mathematical model and a computational method for unsteady combustion rate of a composite metallized solid propellant under conditions of blowing. A flat surface of the metallized propellant burning in an unlimited blowing flow is considered. The model of erosive burning for metallized solid propellants is developed using the boundary layer approximation on the assumption of asymptotic flow regime which accounts for a blowing process in terms of turbulent heat and mass transfer, temperature pulsations, and reagent concentrations. The paper provides a computational and theoretical analysis of the impact of metal powder additives on the combustion rate of metallized solid propellants under conditions of blowing. The combustion rate is presented as a function of the blowing stream velocity.
