Abstract: The technique of analysis the energy and the frequency oscillation sarising in the combustion chamber of a rocket engine is considered. The technique is based on the solution interior ballistics problems in non-stationary statement with the sub sequent frequency analysis in results of calculations.

Keywords: solid propellant rocket engine, intrachamber processes, oscillations of thermodynamic values, Fourier-analysis, Wavelet-analysis.
