Abstract

L’invention concerne un rotor de turbomachine aéronautique, comprenant une aube (11) dont la pale (12) présente un bord d’attaque (31), un intrados (34), une première surface (16) d’extrémité libre. L’aube (11) présente, en intrados (34), au moins une rainure (35) qui définit un amincissement suivant une direction d’épaisseur de la pale et qui s’étend de façon allongée obliquement par rapport à la corde, et ce depuis le bord d’attaque (31). Figure à publier avec l’abrégé : [Fig. 11]
