摘要： 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 noise reducer configured on a surface of the rotor blade. The noise reducer includes a plurality of noise reduction features and a plurality of auxiliary noise reduction features. Each of the plurality of auxiliary noise reduction features is configured on one of the plurality of noise reduction features.

摘要： 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 noise reducer configured on a surface of the rotor blade. The noise reducer includes a plurality of reinforcing members and a plurality of noise reduction features. Each of the plurality of reinforcing members extends outwardly with respect to the rotor blade. Each of the plurality of noise reduction features is connected to one of the plurality of reinforcing members and defines a width. Each of the plurality of reinforcing members causes the connected noise reduction feature to have a variable stiffness throughout at least a portion of the width of the connected noise reduction feature.
