AIRCRAFT GAS TURBINE POWER PLANT Russian patent published in 2018 - IPC F02C7/47 F02C7/12 F02C7/268 F01D25/02 F01D25/12 

FIELD: aircraft engine building.

SUBSTANCE: invention relates to aircraft engine construction, in particular to small-sized gas turbine engines of aircraft. Gas turbine power plant of an aircraft contains an air intake channel in the body with a hollow central fairing, racks and anti-icing device, motor with output shaft, planetary gear with a switching mechanism and a starter generator, located in the cavity of the central fairing and made in the form of a reversible electric machine, stator of which is fixed to the body, and the rotor is connected through the planetary gearbox to the output shaft of the engine. According to the invention, the reversible electric machine is provided with a cooling system with cooling air supply and discharge channels, racks of the air intake channel are hollow, the central fairing is provided with an inner shell, and the anti-icing device is made in the form of an air cavity formed between the shell and the central fairing, connected via a switch to the cooling air outlet channel from the cooling system of the reversible electric machine and connected with the internal cavities of the racks, wherein said cavities of the racks are connected with the air intake channel through calibrated holes formed in the side walls of the racks.

EFFECT: technical result of the invention is to increase the operational reliability and economy of a gas turbine power plant by using heat in the de-icing device obtained in the cooling system of the reversible electric machine.
