Title
(EN) CELLULAR CORE COMPOSITE AIRFOILS
(FR) PROFILS AÉRODYNAMIQUES COMPOSITES À CŒUR CELLULAIRE
Abstract
(EN)
A complex-shaped, three-dimensional fiber reinforced composite airfoil may be formed by using counteracting pressures applied to a structural lay-up of wetted fibers placed onto pressurizable members to form continuous fore and aft loops. In turn, the loops may be structurally functional to transfer loads from an edge of the airfoil to a center section of the airfoil. The airfoil may include may include fillers and/or a metallic insert, wherein the metallic insert may provide a lightening strike capability.
(FR)
L'invention concerne un profil aérodynamique composite tridimensionnel de forme complexe, renforcé par des fibres, qui peut être formé par utilisation de pressions opposées appliquées à un ensemble structural de fibres mouillées placées sur des éléments pouvant être mis sous pression, pour former des boucles avant et arrière continues. Les boucles pour leur part peuvent être structuralement fonctionnelles de façon à transférer des charges d'un bord du profil aérodynamique à une section centrale du profil aérodynamique. Le profil aérodynamique peut comprendre des remplissages et/ou un insert métallique, l'insert métallique pouvant assurer une capacité de protection contre la foudre.
