The paper numerically studies the influence of how the charge channel shape and the law of solid fuel burning rate influence the gas-dynamic vortex flow pattern and pressure self-oscillations in the combustion chamber of a solid-propellant rocket engine. The work presents the findings of the research which show that, using the numerical method, it is possible to choose the optimal shape of the charge channel and the solid propellant grade, which provide the least probability of occurrence of the pulsating combustion regime
