Bladed rotor wheel for a turbine engine

A bladed rotor wheel for a turbine engine, the rotor wheel comprising:

• a disk including, formed in an outer periphery thereof, a slot for assembling a root of a blade;
• and
• a spacer mounted between the blade root and a bottom of the slot, the spacer including
• a member of type that is bistable in position and that can occupy a first stable position for assembly or disassembly in which the bistable member does not exert force on the blade root, and a second stable position which the bistable member exerts a radial force on the blade root for holding the blade stationary and stabilizing the blade in a final position,
• a resilient damper member mounted between the bottom of the slot and the blade root, the blade root configured to bear against the resilient damper member, at least prior to the bistable member occupying the second stable position, and
• a support of elongate shape, including a first zone in which the resilient damper member is mounted and a second zone in which a bistable spring in a form of a resilient strip is mounted, the spring being deformable between the first and second stable positions,
• wherein, in the second zone, the support includes a base and two branches projecting from the base, and the spring is fastened to ends of the branches.
