Abstract[English]
A wind turbine blade (20) that extends longitudinally in a spanwise direction between a root end (24) and a tip end (26), and in a chordwise direction between a leading edge (28) and a trailing edge (30), is disclosed. The wind turbine blade (20) includes a first opposing half-shell portion (34) and a second opposing half-shell portion (36) which together define an interior (38) the wind turbine blade (20), and at least one shear web (52) that extends between the first opposing half-shell portion (34) and the second opposing half-shell portion (36). The wind turbine blade (20) further includes at least one vibration damping device (60, 90, 122, 124, 126, 128, 132, 204, 224, 230, 250) for reducing noise emission from the wind turbine blade (20). The at least one vibration damping device (60, 90, 122, 124, 126, 128, 132, 204, 224, 230, 250) includes at least one resonating member (62, 138, 202, 232, 260) that extends from a surface of the wind turbine blade (20) to a distal end (70, 96, 156, 186, 206, 234, 262) that is configured to oscillate to dissipate vibrational energy away from the surface of the wind turbine blade (20).[French]
L'invention concerne une pale d'éolienne (20) qui s'étend longitudinalement dans une direction d'envergure entre une extrémité d'emplanture (24) et une extrémité de pointe (26), et dans une direction dans le sens de la corde entre un bord d'attaque (28) et un bord de fuite (30). La pale d'éolienne (20) comprend une première partie de demi-coque opposée (34) et une seconde partie de demi-coque opposée (36) qui définissent ensemble un intérieur (38) de la pale d'éolienne (20), et au moins une bande de cisaillement (52) qui s'étend entre la première partie de demi-coque opposée (34) et la seconde partie de demi-coque opposée (36). La pale d'éolienne (20) comprend en outre au moins un dispositif d'amortissement de vibrations (60, 90, 122, 124, 126, 128, 132, 204, 224, 230, 250) pour réduire l'émission de bruit à partir de la pale d'éolienne (20). Le ou les dispositifs d'amortissement de vibrations (60, 90, 122, 124, 126, 128, 132, 204, 224, 230, 250) comprennent au moins un élément résonant (62, 138, 202, 232, 260) qui s'étend d'une surface de la pale d'éolienne (20) à une extrémité distale (70, 96, 156, 186, 206, 234, 262) qui est conçu pour osciller afin de dissiper l'énergie vibratoire à l'opposé de la surface de la pale d'éolienne (20).
