Abstract

One of the ways of improving the efficiency of pressurization systems of fuel tanks of launch vehicles powerplant engines is raising the temperature increase of working body while entering the tank. At the moment 1100 K temperature is reached, but even with usage of this temperature the problem of overheating of aluminum top floor occurred. Attempts to stretch a cloud of overheated gas gave no result due to limiting action of its design using tradition jet input of hot gas into tanks. The extension movement of hot gas injected as vortex circles considering carrier conditions (a range of pressures, tank geometry, time of pressurization work and other) was experimentally investigated. Inject speed ranged 4-10 m/s. Ratios of tank diameter to ring diameter in which limiting action of tank starts showing were found. Frequencies for injection of vortex circles into tank when channeling mode begins are determined. Also main factors that influence on vortex circles range in tank are identified. Main parameters of gas flow in tank after breaking of vortex circles are counted. The obtained results of vortex circles spreading in ranged conditions allow to see the prospects optimistically in using this method of injecting working body with high temperature in free space of powerplant engines fueled tanks. It is appropriate to continue exploring the determination of interaction mechanism of vortex circles and fuel surface, to continue exploring optimal design of vortex circles generator.
