Patent

CA 2758209

A wind turbine blade including a number of segments attached together end-to- end in a predetermined arrange-ment so that the respective covering subassemblies of the segments cooperate to form a substantially smooth surface of the wind turbine blade. Each segment includes a number of fiber tubes extending along preselected lengths of the segment respectively, the fiber tubes being laterally spaced apart from each other respectively to define gaps therebetween. The segment also includes a cov-ering subassembly at least partially supported by the fiber tubes and at least partially defining an internal cavity.

L'invention concerne une pale d'éolienne comprenant un certain nombre de segments fixés l'un à l'autre bout à bout dans une disposition préétablie de sorte que les sous-ensembles de recouvrement respectifs coopèrent pour former une surface sensiblement lisse de la pale d'éolienne. Chaque segment comprend un certain nombre de tubes de fibres s'étendant respectivement sur des longueurs prédéterminées du segment, les tubes de fibres étant respectivement latéralement espacés l'un de l'autre de sorte que des espaces sont formés entre eux. Le segment comprend également un sous-ensemble de recouvrement prenant au moins partiellement appui sur les tubes de fibres et définissant au moins partiellement une cavité intérieure.
