Abstract
A rotor blade for a wind turbine is provided, wherein the rotor blade includes serrations along at least a portion of the trailing edge section of the rotor blade. The serrations include a first tooth and at least a second tooth, and the first tooth is spaced apart from the second tooth. The area between the first tooth and the second tooth is at least partially filled with porous material such that generation of noise in the trailing edge section of the rotor blade is reduced. Furthermore, the embodiments relate to a wind turbine including at least one such a rotor blade.
