TURBOMACHINE ROTOR Russian patent published in 2009 - IPC F01D5/02 F02C7/36

Abstract RU 2375587 C1

FIELD: engines and pumps.

SUBSTANCE: turbomachine rotor relates to aircraft engine production, particularly to attachment of disks on engine shaft. Turbomachine rotor comprises disk with trunnions and shaft with their flanges bolted together and centered along cylindrical mounting surface on said flanges. Aforesaid flange is furnished with cylindrical ledge with radial slits to add to fit along cylindrical surface in rotor rotation. Fit is increased by upping centrifugal load on embraced flange in the zone of mounting cylindrical surface.

EFFECT: tight fit of disk trunnions, relative to shaft, in all operating conditions due to adequate selection of ledge geometry.
