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, the rotor blade further defining a pitch axis; and
,a noise reducer configured on a surface of the rotor blade, the noise reducer comprising a plurality of serrations, each of the plurality of serrations defining a centerline,wherein the centerline of each of the plurality of serrations is in the range between approximately 10 degrees from perpendicular to the pitch axis and approximately perpendicular to the pitch axis.

Abstract
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 further includes a noise reducer configured on a surface of the rotor blade, the noise reducer comprising a plurality of serrations, each of the plurality of serrations defining a centerline. The centerline of each of the plurality of serrations defines a individual tailored angle dependent on at least one of span-wise location, local chord, width, length, bend angle, and thickness
