The purpose of the work is to increase the efficiency of modern gas turbine engines for various purposes of domestic production. The research method is calculated - theoretical with the use of experimental data. The report considers the issues of development and improvement of the method of calculation of thermogasodynamic parameters of the turbocharged gas turbine engine on the basis of the lead description of the blade machines. The mathematical model of TVAD on the basis of the developed method of mathematical modeling with use of one- and two-dimensional approaches to calculation of parameters of the compressor and its approbation at definition of throttle characteristic of the engine is presented. A mathematical description of the features of the working process in a double-circuit turbojet engine with afterburner combustion in the outer circuit on direct-flow modes and the results of numerical simulation of supersonic current from the engine nozzle of a multi-mode aircraft in the accompanying subsonic current. A study of unstable gas-dynamic phenomena in aircraft gas turbine engines is presented and an approach to the diagnosis of the auxiliary state of an axial compressor with a super-rotor device is proposed. The results of research of the ecological questions arising at operation of gas turbine engines of various function, by means of mathematical modeling are presented. The results of research can be used to create mathematical models of high-level engines, including turbocharged, and obtain performance characteristics of specific engines for various purposes, increase the gas-dynamic stability of gas turbine engines and address environmental issues arising during their operation.
