ANALYSES OF THE SOLID PROPELLANT ROCKET MOTOR THRUST FORCE DURING TRANSIENT PROCESSES
Lemić Dragan The solid propellant rocket motor thrust force during transient processes is presented in this paper. A transfer process of a physical value in space and time is therefore considered. Using the Reynolds transport theorem and the moment principle, a rocket motor thrust relation, different from a conventional one for the steady motor regime, is defined. The determination of the dynamic thrust force component using the program for the calculation of interior ballistic parameters in the rocket motor chamber is described.
