Abstract

A wind blade is provided that includes a primary blade body defining a leading edge and a trailing edge and further defining a pressure side and a suction side joining along the trailing edge. The wind blade also includes a secondary blade having an aerodynamic contour defining a first surface and a second surface and coupled with the primary blade body for the purpose of shielding noise. The secondary blade body is disposed proximate to at least a portion of the trailing edge on at least one of the pressure side and the suction side of the primary blade body and may also improve overall performance of the wind blade.
