Abstract[English]
According to the present invention, there is provided a wind turbine blade comprising a trailing edge having a plurality of serrations. Each serration comprises a first trough, a first peak, a second trough, a second peak, and a third trough. A pair of external edges extend from the first and third troughs towards the first and second peaks, at least one of which is convexly curved when viewed normal to the wind turbine blade chordwise and spanwise directions to helps to reduce the size of the space (or "air-10 gap") defined between the adjacent serrations when compared to known solutions.[French]
La présente invention concerne une pale d'éolienne comprenant un bord de fuite présentant une pluralité de dentelures. Chaque dentelure comprend un premier creux, un premier pic, un deuxième creux, un second pic et un troisième creux. Une paire de bords externes s'étendent à partir des premier et troisième creux vers les premier et second pics, dont au moins l'un est incurvé de manière convexe lorsqu'il est vu perpendiculairement aux directions dans le sens de la corde de la pale d'éolienne et dans le sens de l'envergure pour aider à réduire la taille de l'espace (ou "entrefer -10") défini entre les dentelures adjacentes par rapport aux solutions connues.
