Abstract

Etage (30a) d’aubes (32) à orientation variable pour une turbomachine (10) comprenant :- un anneau intérieur (34) ; - un espace (E) axial en amont dudit anneau (34) débouchant dans un circuit de refroidissement (26) ; et- une rangée d’aubes (32) comprenant chacune une pale (32a) s’étendant radialement vers l’extérieur et montée à rotation dans l’anneau intérieur (34) autour de leur axe entre une position ouverte et une position au moins partiellement fermée, chaque aube (32) comprenant un pied (32b) situé à une extrémité intérieure de ladite pale (32a), ledit pied (32b) étant logé dans l’anneau intérieur (34). Ledit étage comprend un organe (40) de régulation du débit d’air configuré pour forcer le passage du flux d’air dans l’espace (E) lorsque les aubes (32) sont en position au moins partiellement fermée.
