    摘要: A vortex generating foil (26A-G) extending from an aerodynamic surface (22) of a wind turbine blade (20), the foil having a nest shape (43A, 43F-G) along a suction side (32A-G) of the foil effective to reduce flow separation between the foil and a leading edge vortex (27, 29) formed in a flow passing over the foil. The nest shape may be formed in part by a progressive fillet (42) between the suction side of the foil and the suction side of the wind turbine blade. The nest shape may be formed in part by a distal portion (40C-D) of the foil curling over the suction side of the foil. A trailing edge fillet (52E-G) may form a ridge (54E-G), which may extend the nest shape aft of the trailing edge of the foil. A nest shape axis (50E-G) may diverge from an incidence angle (φ) of the foil.

    摘要: A load and noise mitigation system (40) for attachment to a wind turbine blade (20). The system (40) includes a flex member (42) for attachment adjacent the trailing edge (28) of the blade (20) and a noise reduction member (44) associated with the flex member (42). At least a portion of the flex member (42) is configured to deform and change in orientation from a first position (58) to a second activated position (60) in the presence of an air pressure force on at least a portion of the flex member (42).
