FIELD: aviation.
SUBSTANCE: aircraft power plant consists of an input device (1), a turbocharger (2) with the air bleed compressor for the turbine blades cooling, an output device (3). The air is cooled in the air-to-air cooler (4), which has the dividing surface in the form of the aircraft cover, under which the air ducts combined with input (5) and output (6) receivers to which the air is supplied and discharged are placed. Receivers (5, 6) are interconnected by a supercharger (7), which pumps a part of the air from the output (6) receiver to the input (5) receiver.
EFFECT: invention improves flight performance and the cnical characteristics of the aircraft.
