Title
(EN) JOINT INTERFACE FOR WIND TURBINE ROTOR BLADE COMPONENTS
(FR) PROCÉDÉS DE FABRICATION DE COMPOSANTS DE PALE DE ROTOR D'ÉOLIENNE
Abstract
(EN)
A rotor blade component for a wind turbine includes a first structural component, such as a spar cap, formed from a plurality of stacked pultruded members. A second structural component, such as a shear web, is fixed to the first structural component at a joint interface. One or more webs form the joint interface, wherein each of the webs has a first section bonded between at least two of the pultruded members in the first structural component and a second section extending across the joint interface and bonded onto or into the second structural component.
(FR)
Un composant de pale de rotor pour une éolienne comprend un premier composant structurel, tel qu'une semelle de longeron, formé à partir d'une pluralité d'éléments pultrudés empilés. Un second composant structurel, tel qu'une âme de cisaillement, est fixé au premier composant structurel au niveau d'une interface d'articulation. Une ou plusieurs âmes forment l'interface commune, chacune des âmes ayant une première section liée entre au moins deux des éléments pultrudés dans le premier composant structurel et une seconde section s'étendant à travers l'interface de joint et liée sur ou dans le second composant structurel.
