LOAD MITIGATION DEVICE FOR WIND TURBINE BLADES
(FR)
DISPOSITIF DE RÉDUCTION DE CHARGE POUR PALES D'ÉOLIENNES
Abstract:
(EN)
The present invention includes a rotor blade (20) having a blade body (30) with a leading edge (26) and a trailing edge (28) and opposed first and second surfaces (34, 36) extending there between defining an airfoil shape (32) in cross-section. A passageway (42) extends through the blade body (30) between the first and second surfaces (34, 36). A flexible member (60) is sealed over one end (50) of the passageway (42). Advantageously, the flexible member (60) is passively responsive to changes in a differential pressure between the first and second surfaces (34, 36) to move between a deactivated position (62) and an activated position (64) where the flexible member (60) extends away from the airfoil shape (32) to function as a load mitigation device (40) for the wind turbine rotor blade (20).
(FR)
La présente invention comprend une pale de rotor (20) comprenant un corps de pale (30) présentant un bord d'attaque (26) et un bord de fuite (28) et des première et seconde surfaces opposées (34, 36) s'étendant entre eux et définissant une forme de plan de sustentation (32) en coupe transversale. Un passage (42) s'étend à travers le corps de pale (30) entre les première et seconde surfaces (34, 36). Un élément flexible (60) est scellé sur une extrémité (50) du passage (42). L'élément flexible (60) réagit avantageusement de façon passive à des changements de pression différentielle entre les première et seconde surfaces (34, 36) en se déplaçant entre une position désactivée (62) et une position activée (64) dans laquelle l'élément flexible (60) s'étend depuis la forme de plan de sustentation (32) pour faire office de dispositif de réduction de charge (40) pour la pale de rotor d'éolienne (20).
