Abstract (en)
The disc has axial grooves (22) for mounting and retaining the vane roots, and deformable zones (34) radially located outside the grooves, where the zones are placed at a rear end of the grooves. The zones having cavities are formed in hooking flanges (36) of inter-vane platforms, and are placed at the level of the rear notches of the vane roots, where the platforms orient air flow at inlet of a turbomachine.
