The paper introduces a mathematical model for calculating the gas-dynamic parameters in the launch container. The model takes into account chemical interactions between the main components of the combustion products, i.e. carbon monoxide and hydrogen, and oxygen. The resulting energy can be used to increase the initiating pulse of the rocket. Within the research, we described the basic requirements for the grid model, and analyzed the accuracy of the results obtained. Furthermore, we compared calculation data of pressure in the launch container with the results of the known method. Findings of research show that the use of two-dimensional and three-dimensional models makes it possible to obtain not only medium-volume gas-dynamic parameters, such as pressure, temperature, density, but also the distribution of these parameters over the computational domain. The developed method of numerical simulation will allow us to estimate the effect of changes in the configuration of the sub-rocket volume and other parameters on the dynamics of the rocket movement without conducting an expensive experiment
