Embodiment Construction

[0024] figure 1 An axial section through the turbojet engine 1 is shown. The turbojet engine 1 comprises a front fan 2 with a rotor arranged into a fan housing 3 which defines a secondary flow. The fan rotor 2 is fastened to the low pressure compressor 4 . The fan 2 and low pressure compressor assembly are fastened via a central shaft to a turbine assembly forming a low pressure turbine 8 .

[0025] Downstream of the low-pressure compressor 4 , the air is further compressed by a high-pressure compressor 5 . The high-pressure compressor 5 is fastened in rotation to a high-pressure turbine stage 7 that drives it. The compressed air enters the combustor 6 which produces hot gases to drive the turbine stages.

[0026] The invention relates in this example to the part of the engine located between the fan rotor 2 and the low-pressure compressor rotor 4 .

[0027] figure 2 The interior of this area is shown in perspective, with the fan blades omitted.

[0028] The fan disk 2...

Abstract

The present invention relates to a turbomachine rotor comprising a disc (20) with a rim and axial slots (21) machined in the rim for the individual housing of blades, a ring (43) being attached to one face of the rim, the ring being pierced with holes (44) in the axial continuation of the slots, at least some of said holes (44) in the continuation of the slots comprising a plug (50), characterized in that the plug is formed by a first half-plug (51) made of a first wear-resistant material and by a second half-plug (52) made of a second material, one of the two half-plugs bearing on one side of the ring (43) and the other bearing on the other side of the ring (43) and being connected to one another through the hole (44). The invention also relates to a plug designed to form an anti-wear device.

Description

technical field [0001] The present invention relates to the field of turbojet engines, in particular to turbojet engines with front fans. Background technique [0002] The rotor of a turbofan fitted to an engine of a civil aircraft comprises a disc driven by a low pressure shaft. A plurality of blades extend radially from the periphery of the disk, the blades being held by their ends forming the roots. In a common type of construction, the blade root has a dovetail-shaped section and the blade is received axially in a recess machined in the edge of the disk. The low pressure compressor is located immediately downstream of the fan disc and forms the same rotor. The low pressure compressor is in the form of a drum comprising multiple stages of vanes. The fan disc is fastened to the low pressure compressor drum by bolting to the radial flange of the low pressure compressor. The flange is also provided with notches to form a mechanism for axially retaining the fan disc blade...
