Noise reduction tab and method for wind turbine rotor blade

摘要

Rotor blade assemblies (100) for wind turbines and methods for reducing rotor blade noise are disclosed. A rotor blade assembly (100) includes a rotor blade (16) having external surfaces defining a pressure side (22), a suction side (24), a leading edge, and a trailing edge (28) extending between a tip (32) and a root (34). The rotor blade further defines a span (44) and a chord (42). The rotor blade assembly (100) further includes a tab (110). The tab (110) includes an inner surface (112), an outer surface (114), a forward end (116) and an aft end (118). The inner surface (112) is mounted to one of the pressure side or the suction side. The outer surface (114) has a cross-sectional profile configured to modify an operational value of the rotor blade (16) at the trailing edge (28). The forward end (116) is disposed within the chord (42).
