    摘要: A rotor blade assembly for a wind turbine and a method for increasing a loading capability of a rotor blade within a maximum load limit for a wind turbine are 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 assembly further includes an extension connected to a surface of the rotor blade, the extension having at least one design characteristic configured for increasing a loading capability of the rotor blade within a maximum load limit for the wind turbine. The design characteristic is one of extension length, extension width, extension curvature, span-wise extension location, chord-wise extension location, or extension angle with respect to a chord line of the rotor blade.

    摘要: A wind turbine rotor blade assembly includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. An edge extension is attached along the trailing edge and includes a first strip member having a span-wise attachment section attached to pressure side, and a second strip member having a span-wise attachment section attached to the suction side. Each of the first and second strip members has an outboard edge and an extension section that projects chord-wise beyond the trailing edge. The extension sections are adhesively attached to each other outboard of the trailing edge along a span-wise length of the first and second strip members and define an adhesively bonded closure edge of the edge extension. A method is also provided for forming an edge extension on a wind turbine rotor blade.
