Abstract
The bearing supporting the rotor has its stiffness increased by being connected directly to a foundation, thereby providing better behavior for the bearing in the event of a major accident (e.g. the loss of one of the blades in the last, or lowest presssure stage). In addition, by separating the bearing function from the stator exhaust end function, there is no danger of any rotor out-of-balance forces exciting resonance in the stator structure.
