Abstract

La présente invention concerne une aube comprenant une pale (7) à profil aérodynamique comprenant une première peau (21) et une deuxième peau (21) en vis-à-vis, les peaux (21) présentant chacune une face interne (22) délimitant entre elles une cavité (23) et étant réalisées dans un matériau composite comprenant un renfort fibreux (20) obtenu par tissage tridimensionnel et une matrice comprenant une matière plastique dans laquelle est noyé le renfort fibreux (20). L’aube comprend également un ensemble de raidisseurs (30) monolithique avec les peaux (21) et s’étendant à travers la cavité (23) en étant fixé sur la face interne (22) de la première peau (21) et de la deuxième peau (21) de sorte à les relier. Figure pour l’abrégé : Fig. 3aThe present invention relates to a blade comprising an aerodynamically profiled blade (7) comprising a first skin (21) and a second skin (21) facing each other, the skins (21) each having an internal face (22) delimiting between them a cavity (23) and being made of a composite material comprising a fibrous reinforcement (20) obtained by three-dimensional weaving and a matrix comprising a plastic material in which the fibrous reinforcement (20) is embedded. The blade also comprises a set of stiffeners (30) monolithic with the skins (21) and extending through the cavity (23) while being fixed on the internal face (22) of the first skin (21) and of the second skin (21) so as to connect them.
