<p>The invention relates to a turbine wheel in a turbine engine, the wheel comprising a disk having a plurality of blades with roots that are axially engaged and radially retained in longitudinal slots in the outer periphery of the disk, the blades having platforms that extend circumferentially end to end and that are radially facing longitudinal teeth of the disk that define the slots. Protection members for protecting the flanks of the slots and made out of sheet metal are mounted on the teeth of the disk and held thereon by co-operating shapes, the protection members including means for bearing radially against the platforms of the blades in order to oppose circumferential tilting of the blades, and they also include means for at least partially closing the radial gaps between the teeth and the platforms of the blades.</p> |
