Four-terminal networks method, impedance method and finite elements method are used. New models of different pipes of oxidant, which contains stepped pipes, collectors, air-to-electric waves, is developed. New mathematical model of liquid-gas damper is obtained and simple approach for choice of damper parameters is suggested. The vibrations of rockets frames using beam finite elements and shell models are analyzed. The results of this project is used in Ukraine rockets industry.
