ABSTRACT:
A rotor blade assembly for a wind turbine is disclosed. The rotor blade assembly includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root, the rotor blade further defining a pitch axis. The rotor blade assembly further includes a noise reducer mounted to the rotor blade. The noise reducer includes a base plate defining a base line, a plurality of noise reduction features extending from the base line, and a plurality of apertures defined in the base plate. Each aperture is positioned on an opposite side of the base line from the plurality of noise reduction features such that the aperture is fully defined in the base plate.
