Abstract (en)
The system comprises a wall (21) integral with a concrete raft (5) equipped with a circular orifice (22), through which the outlet (1) passes, and ties or arms (12) pass through the wall of the outlet and are fastened to the wall in order to support the bearing (7) on the outlet side. <??>An increase in the rigidity of the bearing (7) supporting the rotor makes it possible to ensure a higher stability of the bearing towards major accidents, for example, the loss of a last blade (BP). <??>Furthermore, as a result of the separation of the bearing function from the outlet bottom function of the stator, any unbalance of the rotor cannot excite a natural mode of the structure of the stator. <IMAGE>
