In offered work in three-dimensional cylindrical statement by realization of direct computing experiment the real oscillatory process is reproduced and the mechanism of occurrence and support of low-frequency acoustic instability in the rocket engine on firm fuel with the complex (compound) chamber of combustion tandem of a type is investigated. The direct numerical modeling will be carried out by the Davydov’s method (method of large particles), it is good itself recommending at the decision of many tasks of the mechanics of continuous environments. The results of numerical accounts are resulted. The results will well be coordinated to experimental data. The deeply nonlinear nature of low-frequency acoustic fluctuations of pressure and draft connected to structure and character of current in the chamber of combustion of the rocket engine on firm fuel proves to be true gas dynamics.

Propagation of the moving waves in geometrical – nonlinear continuum with dislocations have been analyzed in this work. A diagram which shows us with which frequency and wave number it is possible the modulation unstable of the waves has been drawn.
