A rotor disk (,) is arranged between two stator disks (,), the disks being made in thermostructural composite material at least for the wear parts. A first supporting structure (,) has a bell shape with a bottom part (,) whereon rests the first stator disk (,) and part of the skirt (,) linked to the bottom part (,) and encloses the disks (,), the bell-shaped structure having cooling means (,) for evacuating the heat generated by the mutual friction of the disks. A second supporting structure (,) has a part in the shape of an annular support plate whereon rests the second stator disk (,); and the bell-shaped structure bottom part (,) and the support plate (,) are provided with cotters (,) or radial ribs (,) co-operating with the corresponding radial housings (,) formed in the outer surfaces (,) of the stator disks (,) to block the latter in rotation relative to the supporting structures (,).
