Abstract

L'invention concerne une roue (4) d'aubes redresseuses du flux secondaire d'un moteur d'aéronef, tel qu'un turboréacteur, qui comprend une pluralité d'aubes redresseuses du flux secondaire, structurelles (40), en matériau composite, ayant chacune une pale (41), un pied d'aube (42) et une tête d'aube (43), lesdits pieds d'aubes étant fixés sur un moyeu (3) de ladite roue et lesdites têtes d'aubes sur une virole externe (5) de ladite roue, lesdites aubes redresseuses (40) s'étendant radialement autour de l'axe longitudinal de ladite roue (4). Cette roue est remarquable en ce qu'une pièce intermédiaire (6), configurée pour pouvoir se déformer par flambement, est intercalée radialement entre chaque pied d'aube (42) et le moyeu (3) et/ou entre chaque tête d'aube (43) et la virole externe (5), le seuil de flambement de ladite pièce intermédiaire (6) étant inférieur au seuil de rupture mécanique par flambement de ladite aube.
