This paper presents three-dimensional numerical modeling of the processes occurring in the combustion chamber of a hybrid engine. Numerical simulation using verified author's code was carried out. The distributions of temperature, pressure, longitudinal and transverse velocities were analyzed. The characteristic features of the regression rate were studied. The influence of the reaction kinetics on the nature of the processes in the combustion chamber was determined. The obtained numerical results were compared with experimental data.
