The problem of one-dimensional motion of gas in thecombustion chamber of the liquid rocket engine, taking into account its heat exchange with the chamber wall and with the cooling liquid, is considered in the article. The results of calculating the cooling of the chamber obtained by numerically solving the system of differential equations of gas dynamics combined with the heat balance equation are presented. The analysis of the results allows to assert about the possibility of applying the proposed method in practice.
