Abstract

La présente invention concerne une aube (25) de redresseur (23) de turbomachine, d'une hauteur (H) s'étendant entre un pied d'aube (26) et une tête d'aube (27) selon une direction radiale (Z), ladite aube (25) comprenant une succession de cinq parties bombées suivant une direction tangentielle (Y) perpendiculaire à la direction radiale (Z), cette succession de partie bombées s'étendant sur toute la hauteur (H) de l'aube (25), et la convexité des parties bombées successives étant alternativement dans un sens et dans l'autre. L'aube (25) a pour avantage d'avoir une fréquence propre pour le premier mode de vibration à bandes qui est différente des fréquences de sollicitation de ladite aube (25), lors du fonctionnement de la turbomachine.
