Kotkin V. The method of calculating the characteristics of the gas turbine engine nozzle of the multi-mode aircraft in the conditions of the subsonic external flowing

Research object - aviation gas turbine engine nozzle gasdynamic processes; research objective - the calculation method creation of multi-mode aircraft gas turbine engine nozzle characteristics in the conditions of the subsonic external flow for decreasing the losses of nozzle thrust by a choice of nozzle geometrical parameters; research methods - flows numerical modeling methods and integrated nozzle parameters calculation methods; practical results - nozzle characteristics in the external flow conditions, geometrical parameters and the nozzle control law, improvement of design quality; novelty - the calculation method of multi-mode aircraft gas turbine engine nozzle characteristics in the conditions of the subsonic external flow, which takes into account viscous interaction of streams on an exit from the engine was designed, streams interaction influence on nozzle thrust losses was estimated, the optimal nozzle geometrical parameters with subject to streams interaction were received; introduction - at the Ukraine Armed Forces Kharkov Air Forces Institute and at the Kharkov military university; use branch - jet engine-building.
