Abstract

La présente invention concerne un rotor (2) de turbine de turbomachine d’aéronef, comprenant un disque de rotor (3) muni à sa périphérie d’une pluralité d’alvéoles (30) de réception du pied (42) d’une aube (4). Ce rotor est remarquable en ce que chaque aube (4) comprend une nervure d’accouplement circonférentielle, en ce qu’il comprend une pluralité de plateformes (5), qui comprennent une paroi principale (50) qui se prolonge à ses deux extrémités par une paroi radiale amont (51) et par une paroi radiale aval (52), les deux bords longitudinaux de chaque plateforme comprenant une gorge (504) de réception d’une partie de ladite nervure d’accouplement de l’une des deux aubes (4) entre lesquelles cette plateforme (5) est assemblée et en ce que la hauteur de chaque paroi radiale amont (51) est telle qu’il s’étend radialement vers l’intérieur au-delà du fond de l’alvéole (30), jusque devant la face amont (32) du disque de rotor (3). Figure pour l’abrégé : Fig. 7
