Abstract

L’invention concerne un ensemble redresseur (30) d’une turbomachine, comprenant :- une virole interne (10) d’un carter comprenant, depuis un axe de rotation de la turbomachine, une surface radialement externe (11) comprenant une alternance de fentes (12) et de traverses (13), les traverses (13) s’étendant axialement, - au moins une aube (4) redresseuse comprenant un pied d’aube (41) agencée dans une fente (12) ;- au moins une lamelle (20) comprenant une partie centrale supportée par la traverse et des parties latérales (22, 23) s’étendant depuis la partie centrale et suspendues dans les fentes (12) entourant chaque traverse ;- au moins une ailette (5) comprenant une plateforme (51) disposée au-dessus de chaque traverse (13) ; chaque traverse (13) comprend une encoche formant un renfoncement radial dans la traverse (131) et ménagée, au milieu de la traverse (13) pris selon un une direction axiale, l’encoche supportant ladite lamelle (20), chaque lamelle (131) étant apte à être déformée par un pied d’aube (41) de manière à ce que la partie centrale se déforme pour combler un jeu radial entre la traverse et l’ailette (5) disposée entre chaque aube.
