ROTOR BLADE WITH SERRATIONS

摘要

The invention relates to a rotor blade (20) for a wind turbine (10), wherein the rotor blade (20) comprises serrations (30) along at least a portion of the trailing edge section (23) of the rotor blade (20). The serrations (30) comprise a first tooth (31) and at least a second tooth (32), and the first tooth (31) is spaced apart from the second tooth (32). The area (35) between the first tooth (31) and the second tooth (32) is at least partially filled with porous material such that generation of noise in the trailing edge section (23) of the rotor blade (20) is reduced. Furthermore, the invention relates to a wind turbine (10) comprising at least one such a rotor blade (20).
