Abstract

Procédé d’appairage amélioré d’un bord d’attaque métallique et d’un corps d’aube composite Procédé d’appairage d’un bord d’attaque métallique et d’un corps d’aube composite, dans lequel on fournit un corps d’aube (10) réalisé en matériau composite, comprenant une portion d’attaque, et on fournit un bord d’attaque (30) métallique présentant une face interne (32) et une face externe (34), adapté pour être solidarisé à la portion d’attaque du corps d’aube via sa face interne (32), on recouvre la portion d’attaque du corps d’aube (10) d’un matériau conducteur (20), on usine une face interne du bord d’attaque métallique par électroérosion par enfonçage du corps d’aube (10) dans le bord d’attaque (30), le corps d’aube (10) étant relié à une source de courant pour former une électrode du procédé d’électroérosion. Figure pour l’abrégé : Fig. 2.Improved method of pairing a metal leading edge and a composite blade body Method of pairing a metal leading edge and a composite blade body, in which a body is provided blade (10) made of composite material, comprising a leading portion, and a metallic leading edge (30) is provided having an internal face (32) and an external face (34), adapted to be secured to the attack portion of the blade body via its internal face (32), the attack portion of the blade body (10) is covered with a conductive material (20), an internal face of the edge is machined metal attack by electroerosion by driving the blade body (10) into the leading edge (30), the blade body (10) being connected to a current source to form an electrode of the electroerosion process. Figure for abstract: Fig. 2.
