Abstract. The article examines approaches to modeling the combustion process of high-energy pasty pro-pellants. A physical picture of the combustion process is presented. A mathematical framework is devel-oped that accounts for the influence of the thickness and porosity of an intermediate structure in the com-bustion zone – the skeleton layer (SL). A multi-parameter optimization problem is formulated as a tool for the study. A sequence for applying the optimization procedure to propellant formulations is defined, taking into account the specific features of their combustion processes. Simulation results are obtained that con-firm the validity of the adopted assumptions. Directions for further research are identified.

Keywords: propellant, conventional propellants, burn rate, skeleton layer, propellant structure, pasty propel-lant
