    摘要: A slat (30) extending along an inboard portion of a wind turbine main blade element (22). The slat may have an end vortex modification appendage, such as winglet (34), endplate (64), raked wingtip (70), or down turned wingtip (72), and may be located behind a line defined perpendicular to a mean camber line of the main blade element at a leading edge of the main blade element. At least the leading edge (42S) of the slat may be disposed within a zone (48) of airflow that generally parallels the suction side (40) of the main blade element. The slat may have a flatback trailing edge (44F). Vortex generators (60) may be attached to the slat. Slats may be retrofitted to a wind turbine rotor (20) by attaching them to the spar caps (56) of the blades or to the hub (26) of the rotor.

    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.
