Abstract[English]
Serrated Trailing Edge Device A wind turbine blade assembly comprises a wind turbine blade (10) and a serrated device (20) attached at the trailing edge (14) of the blade. The serrated device has a two-part construction and comprises a first panel (24) having a mounting portion (28) and a slitted portion (30) comprising a plurality of first teeth (32) defined between the slits (34); and a second panel (26) having a mounting portion (44) and a slitted portion (46) comprising a plurality of second teeth (48) defined between the slits (34). The mounting portion of the first panel is attached to one of the pressure side (16) or the suction side (18) of the wind turbine blade in the region of the trailing edge. The mounting portion of the second panel is attached to the other of the pressure side or the suction side of the wind turbine blade in the region of the trailing edge. The slitted portion of the first panel is connected to the slitted portion of the second panel such that the slits of the first panel are aligned with the slits of the second panel and the first teeth are aligned with the second teeth. Each second tooth of the second panel is connected to a respective first tooth of the first panel to form a respective serration (22) of the serrated device.[French]
L'invention concerne un ensemble pale d'éolienne qui comprend une pale d'éolienne (10) et un dispositif dentelé (20) fixé au niveau du bord de fuite (14) de la pale. Le dispositif dentelé présente une construction en deux parties et comprend un premier panneau (24) présentant une partie de montage (28) et une partie fendue (30) comprenant une pluralité de premières dents (32) définies entre les fentes (34); et un second panneau (26) présentant une partie de montage (44) et une partie fendue (46) comprenant une pluralité de secondes dents (48) définies entre les fentes (34). La partie de montage du premier panneau est fixée à l'un du côté pression (16) ou du côté aspiration (18) de la pale d'éolienne dans la région du bord de fuite. La partie de montage du second panneau est fixée à l'autre côté parmi le côté pression ou le côté aspiration de la pale d'éolienne dans la région du bord de fuite. La partie fendue du premier panneau est reliée à la partie fendue du second panneau de telle sorte que les fentes du premier panneau sont alignées avec les fentes du second panneau et les premières dents sont alignées avec les secondes dents. Chaque seconde dent du second panneau est reliée à une première dent respective du premier panneau pour former une dentelure respective (22) du dispositif dentelé.
