Abstract: The paper presents estimates of the dynamic characteristics of unsteady combustion of a solid rocket propellant in a combustion chamber with in pressure is varied automatically by a specified program. The estimates are obtained from experimental data by mathematical modeling with the use of a simplified model of unsteady processes in the combustion chamber. A linear approximation is obtained for the transfer function of the unsteady-combustion rate, and its coefficients are expressed analytically in terms of the parameters of a simplified model of unsteady processes. Results of identification of the model for several fragments of experimental processes are given. Families of approximate frequency characteristics of the unsteady-combustion rate are constructed, analyzed, and compared with available results.
