FIELD: turbines or turbomachines.
SUBSTANCE: two-circuit turbojet engine consisting of an input device, a fan, an internal circuit and an external circuit. Compressor, combustion chamber, turbine, gas channels of heat exchanger-regenerator, exhaust branch pipe are located inside internal circuit. Inside the external circuit there are air channels of heat exchanger-regenerator, nozzle. Exhaust pipe is located at the fan inlet.
EFFECT: invention allows increasing pressure drop in turbine, transferring all heat from internal circuit to external circuit thus increasing overall efficiency.
