Abstract
L’invention concerne un module de turbomachine d’axe longitudinal X, comportant une hélice (2) non carénée entrainée en rotation autour de l’axe longitudinal X et au moins un redresseur (25) comprenant une pluralité d’aubes de stator (26) à calage variable s’étendant suivant un axe radial Z perpendiculaire à l’axe longitudinal X depuis un carter fixe. Selon l’invention, le module comprend un premier système de changement des pas (30) des pales des aubes de stator (26) qui comprend : - au moins un premier moyen de commande (31) comportant un premier corps fixe (75) relié au carter fixe et un premier corps mobile (76) axialement par rapport au premier corps fixe, - au moins un premier mécanisme de liaison (32) reliant chaque aube de stator (26) au premier corps mobile (76) du premier moyen de commande (31), le premier mécanisme de liaison (32) comprenant : - - un anneau de liaison (30), centré sur l’axe longitudinal, relié aux pieds (28) de chaque aube de stator et - - au moins un levier (73) relié d’une part, à l’anneau de liaison (60) et d’autre part, au premier corps mobile (76) du premier moyen de commande.
