METHOD OF GAS-TURBINE ENGINE SUPPORTS SUPERCHARGE Russian patent published in 2009 - IPC F02C7/06 

FIELD: motors and pumps.

SUBSTANCE: invention is related to the field of gas-turbine engine manufacturing, namely, to methods of gas-turbine engine supports supercharge. Method of bypass gas-turbine engine supports supercharge consists in supply of air from one of compressor steps via stands of intermediate body of compressor into pre-oil cavity of low pressure compressor back support and via communicated air-ducts into pre-oil cavities of low pressure compressor front support, front support of high pressure compressor and turbine support. When high pressure rotor rotates at frequency close to frequency of its rotation at the mode "low gas", air is supplied via stands of compressor intermediate body from high pressure compressor, at that air is additionally supplied directly to pre-oil cavity of turbine support from one of the last stages of compressor or from air gas channel downstream the last stage of compressor via breathing line of turbine support.

EFFECT: higher reliability of engine operation and increase of its resource.
