Abstract

Dispositif pour l'introduction des efforts de traction et longitudinaux dans un élément de construction de type sandwich, en particulier d'une coque de pale de rotor, muni d'alésages transversaux pour des boulons de fixation et comportant, placé entre deux peaux de couverture en matière plastique renforcée de fibres, un noyau support flexible pour tenir compte des efforts de traction. Dans la zone de chaque alésage transversal 4, le matériau du noyau est remplacé par un tissu de fibres 6 imprégné de résine synthétique et dans un passage 11, subsistant dans la zone du plan médian rapporté à l'épaisseur de la pièce de construction, s'étend librement un moyen de traction (boulon d'assemblage) qui, pour l'introduction des efforts, agit sur le boulon de fixation 5.Device for introducing tensile and longitudinal forces into a sandwich-type construction element, in particular a rotor blade shell, provided with transverse bores for fixing bolts and comprising, placed between two cover skins made of fiber-reinforced plastic, a flexible support core to take into account tensile forces. In the area of each transverse bore 4, the core material is replaced by a fabric of fibers 6 impregnated with synthetic resin and in a passage 11, remaining in the area of the median plane relative to the thickness of the construction part, s 'freely extends a traction means (assembly bolt) which, for the introduction of forces, acts on the fixing bolt 5.
