Abstract. This paper presents the mathematical model describing a nonstationary combustion of metallized solid propellant. The model takes into account the heat transfer, the oxidizer decomposition and gasification of the solid propellant, two-phase, dual-velocity, two-temperature reactant flow over the propellant surface. The conditions on the surface perform the conservation of energy and mass fluxes. The model is based on the research works [1,2]. Our research provides data of the non-stationary burning rate depending on the Al powder dispersion and the pressure drop value.
