Abstract

La présente invention concerne un étage d'une turbine ou d'un compresseur, avec une pluralité d'aubes qui sont montées sur un rotor et/ou un stator de l'étage. Selon l'invention, les aubes sont réunies en un certain nombre de groupes d'aubes formés d'une seule pièce, composés chacun d'au moins deux aubes et dotés d'une unique fixation commune pour le montage du groupe sur le rotor ou le stator.
