Abstract

Aube de turbomachine comportant une pale (42) à surface aérodynamique s'étendant selon une première direction entre un bord d'attaque et un bord de fuite et selon une deuxième direction, sensiblement perpendiculaire à la première direction, entre un pied de l'aube et une tête d'aube, la pale étant réalisée en un matériau composite à matrice organique renforcée par des fibres, et un renfort structurel métallique (40) collé par un joint de colle (46) sur le bord d'attaque de la pale, le renfort structurel métallique étant constitué d'une partie pleine ou nez sans prolongement d'ailettes épousant la surface aérodynamique de la pale et dont la fixation à la pale avant collage est assurée par un assemblage (44) à tenons et mortaises s'étendant sensiblement selon la première direction.
