NOISE REDUCER FOR ROTOR BLADE IN WIND TURBINE
First Claim
1. A rotor blade assembly for a wind turbine, comprising:
- 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; and
,a noise reducer configured on a surface of the rotor blade, the noise reducer comprising a plurality of noise reduction features, each of the plurality of noise reduction features comprising;
a first surface comprising a first portion mounted to one of the pressure side or the suction side and a second portion configured to interact with wind flowing past the other of the pressure side or the suction side; and
,a second surface interrupting an aerodynamic contour of the one of the pressure side or the suction side.

Abstract
A rotor blade assembly and a method for reducing the noise of a rotor blade for a wind turbine are disclosed. The rotor blade has 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 including a plurality of noise reduction features. Each of the plurality of noise reduction features includes a first surface and a second surface. The first surface includes a first portion mounted to one of the pressure side or the suction side and a second portion configured to interact with wind flowing past the other of the pressure side or the suction side. The second surface interrupts an aerodynamic contour of the one of the pressure side or the suction side.
