Abstract (en)
The system comprises a wall (21) integral with the foundation and having a semicircular orifice (22), in which the lower part of the outlet (1) is accommodated. Ties pass through the wall of the outlet and are anchored at their ends in the wall (21) in the region of the orifice (22). <??>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). <??>Moreover, 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>
