STARTING SYSTEM OF GAS TURBINE ENGINE Russian patent published in 2018 - IPC F02C7/275 F01D25/34 F02C7/32 

FIELD: machine building.

SUBSTANCE: invention relates to the field of gas turbine construction, it can be used in start-up systems of gas turbine engines by means of a shaft-turning device and a starting device, while providing the possibility of connecting via a payload reducer. Starting system contains a gear reducer, a starting device, a shaft-turning device. In the gearbox housing, a shaft connected to the starting device is mounted, on which is mounted a disengaging device with a gear wheel having the possibility of axial movement. Shaft of the swivel device is installed in the gearbox housing, on which is mounted a disengaging device with a gear wheel having the possibility of axial movement. Two gears are installed in the gearbox housing, kinematically connected to each other by means of a gear train, one of which is configured to be connected to the shaft of a gas turbine engine and the other to a payload shaft. Shaft having a connection with the shaft of a gas turbine engine is provided with a gear wheel having the possibility of engaging with the gear of each disengaging device. Invention allows to increase the service life of the reducer of the starting system, and also to increase its reliability.

EFFECT: longer life of the gearbox and higher reliability of the start-up system, lower power consumption, reduced noise.
