摘要： The invention relates to a connection between a first piece (D1) ending in a first ring (12) provided with a succession of holes and notches, the axis of the first ring being centred on the axis of rotation of the compressor rotor in order to be attached to the intake of the compressor rotor, and an assembly formed by a second rotor piece (D2) fixed to a third rotor piece (D2). The second piece (D2) forms the intake of the compressor rotor and ends downstream in a second ring (32) comprising holes. The third piece ends upstream in a third ring (32) comprising holes, and the second and third rings are arranged against each other, so as to place their holes in alignment, and are fixed together by first fastening means. The first circular ring (12) is arranged upstream of and against the second-piece/third-piece assembly so that the notches fit around the first means of fastening the second-piece/third-piece assembly of the rotor and so that at least some of the holes of the first ring are aligned with holes of the second-piece/third-piece assembly, with second fastening means fixing the first circular ring (12) to the second-piece/third-piece assembly.

摘要： The invention relates to a process for manufacturing or repairing a monobloc bladed disc including a stage of forming, on a protruding projection (4) belonging to a disc (1) and extending from an upstream end (4a) to a downstream end (4b) along a protruding projection chord (6), a welded joint surface (8) intended to allow a subsequent stage of fitting a blade (2) by linear friction welding onto the protruding projection (4) of the disc (1). According to the invention, the stage of forming the welded joint surface (8) is carried out in such a way that it includes at least two butt-jointed plane portions (8a, 8b, 8c), arranged in sequence along the protruding projection chord (6). Application to turboshaft engine rotors.
