Abstract:
The invention concerns a novel type of turbomachine. The stator of the turbomachine comprises a plurality of profiled members forming stiffeners arranged on the blade stage. The profiled members are distributed uniformly at periphery of the blade stage and individually between two consecutive blades. The stiffeners are fixed to the internal and external ferrules of the stator in order to uniformly increase the axial and radial stiffness of the stator in normal operation of the turbomachine and to allow the internal ferrules to have a limited displacement during the normal functioning of the turbomachine. This makes it possible to reduce the axial sizing of the turbomachine, and consequently its mass.
