AIRCRAFT POWER PLANT Russian patent published in 2018 - IPC F02K3/04 F02K3/77 

FIELD: aircraft.

SUBSTANCE: aircraft power plant comprises a turbojet bypass engine with external and internal circuits and at least one remote fan module. Remote fan module has a housing with a traction fan installed in it, a fan drive, placed on one shaft, and an adjustable jet nozzle, and is supplemented by an internal circuit with a tapering jet nozzle. This internal circuit is connected by a gas channel to the internal circuit of a turbojet bypass engine and is provided with a device for heating gas coming from the internal circuit of the turbojet bypass engine. Drive of the traction fan is made in the form of a gas turbine located below the device for heating the gas in downstream direction. Walls of the gas channel are made of three layers, where the heat-resistant inner layer is made of an intermetallic compound, the heat-insulating middle layer is made of quartz and silica fabrics, and the outer layer is made of carbon fiber based on high-strength carbon fibers and a high-temperature polymer matrix.

EFFECT: invention provides an improvement in the coordination of take-off and cruising modes of operation and increase in the fuel efficiency of an aircraft power plant.
