Abstract (en)
The disc (32) has guide slots (14) for retaining feet of blades, and inter-blade platforms mounted on ribs (16). Metallic liners (30) are mounted between side walls of the slots and the feet of the blades. The liners have a C-shaped section permitting to engage the liners in translation and to radially retain the liners on the ribs. The section constitutes a locking unit for locking the platforms on the ribs, where the platforms include feet fixed on the ribs. The liners are moved in translation on the ribs between a release position and a retained position of the feet of the platforms.
