The purpose of the study is to analyze the current state of research on the dynamics of promising space, aviation and transport systems. Research methods - methods of mathematical modeling, computational hydrodynamics, oscillation theory, theory of automatic control systems, information-analytical, methods of physical experiment. The following main results were obtained. On the basis of the analysis of literature sources the actual directions of researches of dynamics of perspective liquid rocket engines are defined. A mathematical model for start-up of a test liquid rocket engines with afterburner of generator gas to determine the influence of internal and external factors on the scatter of engine thrust, and an economical method for determining the scatter of internal and external factors influencing the thrust of modern liquid rocket engines with combustion of generator gas. Scientific and methodological support has been developed to determine the influence of design parameters of the vibration protection system on its static and dynamic characteristics. Modern research methods and requirements for aerodynamic improvement of air intake gas turbine engines are considered. Some ways of variation of the closed curves limiting the chosen sections of the channel of air intakes at their aerodynamic optimization are offered.
