Abstract

L'invention concerne une pale. Cette pale est constituée essentiellement par une ossature résistante 2, un élément de remplissage arrière 3, et un revêtement 4; l'ossature 2 est formée par un longeron 5, en écheveaux de stratifils de fibres de verre, s'étendant tout le long de la pale, dont il forme le bord d'attaque, par un noyau 7, en un matériau alvéolaire léger, juxtaposé au côté arrière du longeron 5, et par une nappe 8, entourant complètement 5 et 7, et comprenant au moins une couche de tissus en fibres parallèles de verre, disposées en biais par rapport à l'axe longitudinal de la pale, de manière à former un caisson interne de torsion. L'invention est applicable en particulier aux rotors d'hélicoptère.
