This paper describes the combustion of solid porous propellants, focusing on burning regimes characterized by a convective mechanism of propagation. A new mathematical model of the dynamics of multiphase chemically reacting media, including interphase heat and mass transfer, is developed in the course of the investigation. Mathematical simulations of the process prove theoretically that there exists a self-sustained combustion regime, driven by convection. This regime is supersonic with respect to the gas phase and subsonic with respect to the condensed phase.
