Abstract: The numerical solution of a problem on an activity initial stage of large rocket engines considered. Are used models of chemically equilibrium flow of combustion products. The analysis of results is carried out by comparison with calculations of an internal ballistics problem with on models of the frozen of combustion products.

Keywords: solid propellant rocket engine, intrachamber processes, the «frozen» composition of combustion products, chemically equilibrium.
