Title (EN) VANE COMPRISING A LEADING-EDGE SHIELD AND METHOD FOR PRODUCING SAID VANE
(FR) AUBE COMPRENANT UN BOUCLIER DE BORD D'ATTAQUE ET PROCEDE DE FABRICATION DE L'AUBE
Abstract:
(EN) The invention relates to a vane (16) comprising a vane body (30) made of a composite material having a fibre-reinforced organic matrix, and a leading-edge shield (32) made of a material that has a higher resistance to periodic impacts than the composite material of the vane body. The leading-edge shield (32) is assembled on the vane body (30) and the vane (16) comprises a securing reinforcement (46) stuck to the leading-edge shield (32) and to the vane body (16). The invention also relates to a turbojet comprising a blower provided with such vanes and to a method for producing such a vane.
(FR) L'invention concerne une aube (16) comprenant un corps d'aube (30) en matériau composite à matrice organique renforcée par des fibres et un bouclier de bord d'attaque (32) en un matériau ayant une meilleure résistance aux impacts ponctuels que le matériau composite du corps d'aube. Le bouclier de bord d'attaque (32) est assemblé sur le corps d'aube (30) et l'aube (16) comporte un renfort de solidarisation (46) collé sur le bouclier de bord d'attaque (32) et sur le corps d'aube (16). L'invention concerne également un turboréacteur comprenant une soufflante comportant de telles aubes ainsi qu'un procédé de fabrication d'une telle aube.
