The aim of the fourth stage of the research is theoretical research into the dynamics of a marching liquid rocket engine. Aerodynamic optimization of the input device of a modern aviation GTE. Production and research of experimental versions of anti-vibration systems. Research methods are mathematical modelling, computational fluid dynamics, theory of oscillations, theory of automatic control systems, information-analytical, physical experiment. A mathematical model of high-frequency acoustic oscillations in the combustion chamber of a test rocket engine was developed, and the oscillation parameters were evaluated using finite element analysis. On the basis of the numerical modeling of the spatial turbulent flow in the air intake (AI) of a modern aviation GTE, the optimal shape of the AI channel was determined, taking into account the design limitations. An experimental sample of the anti-vibration system for the protection of the payload and the spacecraft as a whole from vibration and vibration-impulse loads was produced, and experimental studies of this system were carried out to determine its static and dynamic characteristics. It is shown that this anti-vibration system provides protection of the payload from vertical shock loads and vibrational disturbances. Statistical and running tests of the anti-vibration system of the driver's seat of the vehicle in the conditions of the real road surface were carried out. It is shown that the modified pneumatic anti-vibration module developed and used in this system is more effective than existing samples of similar purpose.  Product Description popup.authors Bashlii Inna D.
