Abstract
L'invention concerne un ensemble de redressement d'un flux d'air d'une turbomachine, comprenant deux viroles (30) coaxiales radialement interne et externe, respectivement, entre lesquelles s'étendent des aubes (32) en matériau composite fixées à une première portion d'extrémité (42) à la virole radialement interne et à une seconde portion d'extrémité (44) à la virole (30) radialement externe, les aubes (32) comprenant une partie utile s'étendant entre les deux portions d'extrémité (42, 44). Selon l'invention, pour chaque aube (32), dans un plan perpendiculaire à l'axe des viroles (30) radialement interne et externe, une droite passant par une jonction entre lesdites première et seconde portions d'extrémité (42, 44) et la partie utile forme avec un rayon de la virole radialement interne passant par la jonction entre ladite première portion d'extrémité et la partie utile de ladite aube (32) un angle α tel que 0°<α<90°.
