Abstract

Aube de turbomachine à bord d’attaque métallique intégré et procédé pour l’obtenir . L’invention concerne une aube (20) de turbomachine comprenant un aubage (21) en matériau composite à renfort fibreux densifié par une matrice et un bord d’attaque (21a) métallique intégré, l’aubage s’étendant suivant une direction longitudinale (L), le bord d’attaque (21a) étant formé par un clinquant métallique (30) surmoulé sur l’aubage, ledit clinquant (30) ayant une aile intrados (31) et une aile extrados (32) qui s’étendent respectivement sur les faces intrados (24) et extrados (25) de l’aubage en épousant un profil aérodynamique de l’aube. L’une parmi l’aile intrados (31) et l’aile extrados (32) présente une portion de positionnement (40) s’étendant suivant la direction longitudinale (L), ladite portion ayant une face interne (41) plane et une épaisseur croissante en s’éloignant du bord d’attaque (21a), et étant logée dans une rainure de forme correspondante dans l’aubage. L’invention vise aussi un procédé de fabrication d’une telle aube. Figure pour l’abrégé : Fig. 3.
