Abstract (en)
[origin: WO2012071679A1] A rotor blade assembly for a wind turbine is disclosed. The rotor blade assembly includes a rotor blade having 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 assembly further includes a mounting plate and a noise reducer. The mounting plate is configured on a surface of the rotor blade. The noise reducer may include a base plate and a plurality of noise reduction features. The base plate is mounted to the mounting plate. The plurality of noise reduction features extend from the base plate.
