Title
(EN) WIND TURBINE BLADE COMPRISING VORTEX GENERATORS
(FR) PALE DE TURBINE ÉOLIENNE COMPRENANT DES GÉNÉRATEURS DE TOURBILLONS
Abstract
(EN)
Disclosed is a wind turbine blade (10) and a method for retrofitting a wind turbine blade (10), the wind turbine blade (10) extending in a longitudinal direction (r) along a pitch axis and having a tip end (16) and a root end (14) as well as a blade length (L), the wind turbine blade (10 further comprising a profiled contour including a pressure side (52) and a suction side (54), as well as a leading edge (56) and a trailing edge (58) with a chord (60) having a chord length (C) extending there between, the profiled contour, when being impacted by an incident airflow generating a lift, wherein the suction side (54) of the wind turbine blade is provided with a plurality of vortex generators positioned along a mounting line (36) having a proximal end point (37A) nearest the root end and a distal end point (37B) nearest the tip end, wherein the mounting line (36) is a concave line seen from the trailing edge (58) of the wind turbine blade (10).

L'invention porte sur une pale de turbine éolienne et sur un procédé pour rattraper une pale de turbine éolienne, la pale de turbine éolienne s'étendant dans une direction longitudinale le long d'un axe de pas et ayant une extrémité de bout de pale et une extrémité de pied de pale, ainsi qu'une longueur de pale, la pale de turbine éolienne comprenant en outre un profil qui comprend un côté en pression et un côté en dépression, ainsi qu'un bord d'attaque et un bord de fuite, et une corde ayant une longueur de corde qui s'étend entre les deux bords. Le profil génère une portance lorsqu'il est frappé par un flux d'air incident, le côté en dépression de la pale de turbine éolienne est équipé d'une pluralité de générateurs de tourbillons positionnés le long d'une ligne de montage ayant un point d'extrémité proximale le plus proche du pied et un point d'extrémité distale le plus proche de l'extrémité de bout de pale, la ligne de montage est une ligne concave, vue du bord de fuite de la pale de turbine éolienne.
