Zusammenfassung:	A rotor blade assembly for a wind turbine is disclosed. In one embodiment, the rotor blade assembly includes a rotor blade 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 rotor blade further defines a span and a chord. The rotor blade assembly further includes a noise reducer configured on an exterior surface of the rotor blade. The noise reducer includes a plurality of noise reduction features. Each of the plurality of noise reduction features defines a centerline. In a planform view, the centerline of each of the plurality of noise reduction features is approximately parallel to a local flow streamline for that noise reduction feature at the trailing edge of the rotor blade.
