The object of research is dynamic processes in liquid launch vehicles, in automobile transport and cavitating pumps, technologies of anti-vibration systems and air intakes of gas turbine engines (GTD). The purpose of the work is the development and improvement of mathematical models necessary for conducting research on work processes in rocket, aviation and transport systems. Research methods - methods of mathematical modeling, computational hydrodynamics, theory of oscillations, theory of automatic control systems, information-analytical, physical experiment methods. The following main results were obtained during the research. A method has been developed to determine the spread of the main engine parameters, which best characterize the course of work processes in engine systems and units during the start-up of a test multi-engine propulsion system. The existing approaches to the numerical modeling of three-dimensional turbulent gas flows in the air ducts of gas turbines have been developed: the algorithm for solving the equation for pressure correction in the numerical modeling of spatial gas flows has been modified, and the methodology for constructing calculation grids has been improved. A non-linear mathematical model of dynamic processes in the "vibration protection module - object" system under the action of vibration and shock loads has been developed.
