CONTROL DEVICE FOR GUIDING DEVICES OF A GAS TURBINE ENGINE COMPRESSOR Russian patent published in 2022 - IPC F01D17/16 F04D29/56 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aircraft engine construction, namely to devices for controlling the angular position of the rotary guide vanes of a gas turbine engine compressor (GTE). The expected result is achieved by the fact that in a control device for the guiding devices of a gas turbine engine compressor containing a cylindrical sleeve, at least on a section of the inner surface of which a graphite layer is made, mounted and rigidly fixed in an intermediate housing, in which an axis is mounted on which two levers are rigidly fixed, one of which is connected to the rod of the power cylinder, and the other with the drive of the guiding devices, at the same time, at least one hole and/or groove is made on the section of the outer surface of the axis located directly in the contact zone of the sleeve and the axis, in which at least one graphite element is mounted, spring-loaded to the inner surface of the sleeve by means of a spring.

EFFECT: increase in the wear resistance of the wear surfaces of the claimed device and, as a result, to increase the life of the latter.
