TURBOMACHINE ROTOR AND TURBOJET ENGINE Russian patent published in 2017 - IPC F01D5/32 F04D29/34 

FIELD: machine building.

SUBSTANCE: turbomachine rotor comprises disc with axial recesses on rim, blades installed in recesses, inter-blade flanges installed between recesses, axial wedge installed between blades root and recesses bottom, as well as transverse retainer providing blades axial forward locking in their recesses. Retainer is directed in radial grooves made in recesses side surfaces, and radially rests against axial wedge. Axial wedge is locked in upstream direction, resting against transverse annular element, rigidly connected with disc. Inter-blade flanges are retained in place by means of upstream located ring, containing part making support for tab made on inter-blade flanges. Axial wedge and transverse retainer are not connected to each other. Each axial wedge has radial ridge, forming axial thrust against ring, and transverse retainer comprises axial tab, forming axial thrust for axial wedge. Another invention of group relates to turbojet engine with front arranged fan, containing above mentioned rotor.

EFFECT: group of inventions allows to simplify turbomachine rotor assembly and disassembly.
