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.
