Abstract
The rim of the rotor disk has teeth formed by axial grooves. The grooves accept the bases of the blades, which are radially locked by wedges placed between the root and the bottom of the groove. The blade base is extended by a shank bearing the platform and the blade. The locking device comprises locks provided on at least part of the sides of the spindle, and housing provided in the teeth and shaped in such a way that they interact with the locks when the wedge is placed between the blade base and the bottom of the groove. According to one embodiment, the locks are formed by the portions which extend from a locking part lodged in a notch of the blade base and of the shank.
