Abstract

La présente invention concerne une aube (3) de soufflante (1) en matériau composite d’une turbomachine. Sur une portion (15) de l’aube (7) qui s’étend depuis une limite inférieure (16) située à une distance (d) prédéterminée de l’échasse (6) de l’aube au moins égale à 80 % de la hauteur (h) prédéterminée jusqu’au sommet (11) de l’aube (7), un angle (D) de dièdre mesuré en au moins un point prédéfini de la corde de l’aube (3), situé sur la corde de l’aube (3) au niveau de l’extrémité amont (13a) du nez (13) du bouclier (12), est supérieur ou égal à - 3° et inférieur ou égal à 0°. Figure pour l’abrégé : Fig. 1
