Abstract

The invention relates to a turbine wheel (10) having an axis of rotation (X) and comprising: • a disk (12) having a periphery and a side face (12a); • a plurality of blades (14) assembled on the disk, each blade having a blade root (20) and a first hook (22) oriented radially and defining a first groove (24) that opens radially towards the axis of rotation of the turbine wheel; and • the disk including a series of second hooks (26) oriented radially and defining a second groove (28) that opens radially towards the axis of rotation of the turbine wheel. The invention is characterized by the fact an axial retaining ring (30) for placing in the first and second grooves includes a tab (32) for placing between two adjacent blade roots in such a manner as to limit movements of the ring in azimuth.
