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: Apparatus for detecting aerodynamic conditions of a rotor blade (22) of a wind turbine (10). An acoustic sensor (24) may be remotely located from the rotor blade. The sensor may be focused to monitor a portion of a blade path swept by the rotor blade to detect an aerodynamic condition such as flow separation, and may provide input to a controller (27) for control of a pitch of the blade effective to prevent the flow separation from developing into a full stall condition. One sensor may be focused to monitor blades of more than one wind turbine. A plurality of such sensors in a wind park may be connected to a supervisory controller (120) to predict the propagation of wind conditions progressing through the park.

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).
