Использование: в энергетике, а именно в способах преобразования тепловой энергии в механическую в газотурбинном двигателе, а также в газотурбинных двигателях для повышения КПД двигателя путем снижения потерь на сжатие воздуха. Сущность изобретения: сжимают воздух для горения и подают его в источник нагретого рабочего тела, у которого изменяют термодинамическое состояние, расширяя и закручивая его до ввода в турбину. Затем подают к нагретому рабочему телу воздух для его охлаждения под давлением, по меньшей мере равным давлению нагретого рабочего тела с измененным термодинамическим состоянием, и расширяют охлажденное рабочее тело в турбине для производства полезной работы. В процессе сжатия направляемого в источник нагретого рабочего тела воздуха для горения последний охлаждают теплообменом с воздухом, подводимым к нагретому рабочему телу для его охлаждения. Газотурбинный двигатель имеет турбину, компрессор и источник нагретого рабочего тела, сообщающийся с источником топлива и с компрессором для подачи воздуха для горения топлива и для охлаждения нагретого рабочего тела и имеющий зону расширения и закрутки нагретого тела и расположенную за ней зону смешения нагретого рабочего тела с воздухом охлаждения, сообщающуюся с выходом ступени компрессора, давление за которой по меньшей мере, равно давлению нагретого рабочего тела в зоне смешения. В компрессоре за выходом ступени компрессора, сообщающимся с зоной смешения, размещена холодная сторона теплообменника, горячая сторона которого сообщается с воздухом для горения, направляемым в источник нагретого рабочего тела.Usage: in the energy sector, and in particular in methods of converting thermal energy into mechanical energy in a gas turbine engine, as well as in gas turbine engines to increase engine efficiency by reducing air compression losses. The inventive compress air for combustion and feed it into a source of heated working fluid, which change the thermodynamic state, expanding and spinning it before entering the turbine. Then, air is supplied to the heated working fluid to cool it under pressure at least equal to the pressure of the heated working fluid with a changed thermodynamic state, and the cooled working fluid is expanded in the turbine to produce useful work. In the process of compression of the combustion air directed to the source of the heated working fluid, the latter is cooled by heat exchange with the air supplied to the heated working fluid to cool it. The gas turbine engine has a turbine, a compressor and a source of heated working fluid in communication with a fuel source and with a compressor for supplying air for burning fuel and for cooling the heated working fluid and having a zone for expanding and swirling the heated fluid and an adjacent mixing zone of the heated working fluid with air cooling, communicating with the output of the compressor stage, the pressure behind which is at least equal to the pressure of the heated working fluid in the mixing zone. In the compressor downstream of the compressor stage, which communicates with the mixing zone, the cold side of the heat exchanger is placed, the hot side of which communicates with the combustion air directed to the source of the heated working fluid.
