Abstract

Roue de turbine pour une turbomachine, comprenant un disque portant des aubes (35), et des amortisseurs (30) montés entre les échasses (33) des aubes et destinés à frotter sur les plates-formes de ces aubes pour dissiper leurs vibrations, caractérisé en ce que les aubes sont réalisées en composite à matrice céramique (CMC), et en ce que les amortisseurs sont recouverts d'une couche mince de matériau dur sur au moins une partie de leurs surfaces de frottement sur les plates-formes des aubes, et comprennent des moyens d'étanchéité axiale limitant ou empêchant le passage d'air entre les échasses.
