Title
(EN) ATTACHMENT TO A SANDWICH STRUCTURE ELEMENT
(FR) FIXATION À UN ÉLÉMENT DE STRUCTURE EN SANDWICH
Abstract
(EN)
Disclosed is a wind turbine blade and a method of for attaching one or more components to a sandwich structure element of a wind turbine blade. The Wind turbine blade comprising a bushing inserted through a hole provided through a sandwich structure element, and a first component attached to a first bushing part and an elastically compressible element being arranged between a first component surface of the first component and a first side of the sandwich structure element.
(FR)
La présente invention concerne une pale d’éolienne et un procédé pour fixer un ou plusieurs composants à un élément de structure en sandwich d’une pale d’éolienne. La pale d’éolienne comprend une douille insérée par le biais d’un trou disposé à travers l’élément de structure en sandwich, et un premier composant fixé à une première partie de la douille, un élément élastiquement compressible étant disposé entre une surface du premier composant et un premier côté de l’élément de structure en sandwich.
