METHOD OF REPAIR OF CONTROL GEAR OF GUIDE VANES OF TURBINE COMPRESSOR OF BYPASS GAS TURBINE ENGINE

摘要

FIELD: machine building.SUBSTANCE: method of repair of the control gear of the guide vanes of the turbine compressor of a bypass gas turbine engine includes washing of the friction pairs of parts of the control gear. After washing, the friction pairs of the control gear are lubricated. Washing and lubrication of the friction pairs of the control gears are performed by the supply of a liquid working medium to the friction pairs via the holes in the hollow tube connected by one end to the working medium source, and having at least one curved area. The tube is inserted in the second circuit of the engine via the process hole. Prior to washing and lubrication the position of the tube holes relatively to the friction pairs is checked using an endoscope, also inserted in the second circuit of the engine via the process hole.EFFECT: invention reduces labour intensity and reduces repair time.4 cl, 8 dwg
