Abstract

The dynamics of intrachamber processes in a type of solid propellant rocket engine under consideration is investigated in order to optimize its parameters. The conjugate statement of the problem at the level of setting up a computational experiment is formulated. The results of numerical calculations are presented, which revealed an anomalous feature of the rocket engine firing process.
