Patent

CA 2673544

A wind turbine is disclosed comprising a rotor with wind turbine blades each having a root end connected to a hub of the wind turbine and a tip end, the tip end of each of which being equipped with a winglet extending a distance in a direction perpendicularly to a longitudinal direction of the blade. A new and much more slim design of the outer part of the wind turbine blade is disclosed, i.e. with a shorter chord length designed within a narrow band of values defined with respect to the length of the winglet, i.e. the extension in the direction transverse to the longitudinal direction of the blade.

L'invention concerne une éolienne qui comporte un rotor ayant des pales d'éolienne, chacune ayant un pied relié à un moyeu de l'éolienne et une extrémité, l'extrémité de chacune des pales étant équipée d'une ailette s'étendant à une distance dans une direction perpendiculaire à la direction longitudinale de la pale. L'invention concerne aussi un nouveau modèle bien plus mince de la partie externe de la pale d'éolienne, c'est-à-dire avec une longueur de corde plus courte conçue à l'intérieur d'une bande étroite de valeurs définies par rapport à la longueur de l'ailette, c'est-à-dire l'extension dans la direction transversale à la direction longitudinale de la pale.
