An assembly for a turbine engine extending along an axis, includes a stator, a low-pressure compressor shaft, a low-pressure compressor comprising a rotor comprising a drum rotatably coupled to the shaft of the low-pressure compressor, and a fan comprising a disk rotatably coupled to the shaft of the low-pressure compressor. The drum has a radially internal part rotatably coupled to the shaft of the low-pressure compressor and a radially external part fixed to the radially internal part by means of detachable fixing means. A first axial retention means is configured to axially and detachably retain the disk of the fan relative to the shaft of the low-pressure compressor. A second axial retention means is configured to axially and detachably retain the radially internal part of the drum relative to the shaft of the low-pressure compressor.
An assembly for a turbine engine extending along an axis, including a stator, a low-pressure compressor shaft, a low-pressure compressor including a rotor comprising a drum coupled in rotation to the shaft of the low-pressure compressor, a fan including a disc coupled in rotation to the shaft of the low-pressure compressor, wherein the drum comprises a radially internal portion coupled in rotation to the shaft of the low-pressure compressor and a radially external portion fixed to the radially internal portion via removable fixing means, first axial retention means being configured to axially and removably retain the fan disc with respect to the shaft of the low-pressure compressor, second axial retention means configured to axially and removably remove the radially internal portion of the drum with respect to the shaft of the low-pressure compressor, wherein the first axial retention means include a first stop configured to prevent a displacement of the fan disc with respect to the shaft of the low-pressure compressor in a first direction and a first nut configured to form a second removable stop designed to prevent the displacement of the fan disc with respect to the shaft of the low-pressure compressor, in a second direction, opposite the first direction.
