Developing Ways to Combat Thermal Acoustic Self-Oscillations of Pressure in Fuel Cooling Channels of Engines and Power Plants of Flight Vehicles of Land, Air, Aerospace and Space Application

This article examines specific features of the thermal processes, which take place in cooling and fuel channels of engines, power plants and technical systems of expendable and non-expendable use, working on liquid hydrocarbon fuels and coolants. The positive and negative processes caused by thermo-acoustic self-oscillations of pressure are detailed. Based on the results of experimental research, new ways and methods to combat thermo-acoustic self-oscillations of pressure in the channels of cooling jackets of expendable and non-expendable liquid rocket engines are developed. These methods can also be used in land-, air- and space-based power plants and technical systems that are used in land transport, heavy oil extraction, flight vehicles, space flight vehicles, aerospace planes and orbital space stations.
