Application of the linearization method for solving some problems of internal ballistics

With use of a linearizationís method the mathematical models describing development of indignations in rocket engine are constructed. The equations of the indignant movement are deduced from the equations of one-dimensional equilibrium movement of products of combustion in the chamber of combustion during time, corresponding to an initial stage of work rocket engine. Mathematical models of the indignant movement are applied at the decision of two problems of internal ballistics - to calculation dispersions gas parameters and for definition of own frequencies of acoustic fluctuations rocket engine.
