    摘要: A method of manipulating a boundary layer across a wind turbine rotor blade. The method includes coupling at least one vortex generator to the rotor blade. The vortex generator includes at least one sidewall that extends outwardly a radial distance from an outer surface of the rotor blade. The vortex generator is selectively positionable between a first position and a second position. A control system calculates a condition of the boundary layer. The vortex generator is positioned at one of the first position and the second position based on the calculated condition of the boundary layer for moving the vortex generator between the first position and the second position.

    摘要: A rotor blade for a wind turbine and a method for reducing rotor blade noise are disclosed. The rotor blade includes a body having exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root, the surfaces further defining an interior. The rotor blade further includes at least one purge conduit defined in the tip and configured for exhausting air from the interior such that the air generally reduces noise at the tip.
