Title (EN) COMPOSITE BLADE, COMPRISING A LEADING-EDGE REINFORCEMENT MADE OF ANOTHER MATERIAL
(FR) AUBE COMPOSITE, COMPRENANT UN RENFORT DE BORD D'ATTAQUE EN UN AUTRE MATERIAU
Abstract: front page image
(EN)The invention relates to a blade made of composite material, provided with a reinforcement (17) made of a stronger material with regard to a leading edge (5) likely to be struck by solid objects, which comprises, under the aerodynamic portion of the blade, extensions (18, 19) attached to the blade root. According to the invention, said extensions (18, 19) are dissymmetric, the extension (18) located on the suction side being generally further back from the leading edge (5) than the extension (19) on the pressure side.
(FR)Une aube en matière composite, pourvue toutefois d'un renfort (17), en matière plus résistante à l'endroit d'un bord d'attaque (5) susceptible d'être frappé par des objets solides, comprend, sous la partie aérodynamique de l'aube, des prolongements (18, 19) joints au pied de l'aube. Conformément à l'invention, ces prolongements (18, 19) sont dissymétriques, le prolongement (18)situé du côté de l'extrados, étant généralement plus en arrière du bord d'attaque (5) que celui (19) du côté de l'intrados.
