Abstract

L’invention concerne un ensemble pour un rotor apte à être mobile en rotation autour d’un axe (X), comportant un disque (17) comprenant des alvéoles (16) débouchant en périphérie radialement externe du disque (17), des aubes (12) comprenant des pieds (13) montés avec jeu dans lesdits alvéoles (16), caractérisé en ce qu’un matériau de comblement comportant une mousse polymère (24) remplit au moins en partie le volume (30) délimité par le jeu entre la partie radialement interne d’au moins un pied d’aube (13) et la surface (19) du disque (17) délimitant l’alvéole (16).
