<p>A method of attaching two rotor discs (22) in a turbine engine, the method comprising the steps of: forming a first rotor disc (22) that includes a first axial extension (46) and a disc flange (51); forming a second rotor disc (22) that includes a second axial extension (48) and a weld surface; forming a bridge (53), the bridge (53) including a bridge flange (55) at one end and a weld surface at the other end, and, along an outer radial surface, the bridge (53) comprising means for sealing; attaching the bridge (53) to the second rotor disc (22) via welding the weld surfaces of the bridge (53) and the second axial extension (48); and attaching the first rotor disc (22) to the bridge (53) via removably securing the disc flange (51) to the bridge flange (55).</p> |
