Wind turbine rotor blade with trailing edge extension and method of attachment

A method for forming an edge extension on a wind turbine rotor blade, the rotor blade having a pressure side shell member, a suction side shell member, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root, the method comprising;

• attaching a first strip member to the pressure side shell member along the trailing edge of the blade such that a span-wise section of the first tape member defines an extension section that extends chord-wise beyond the trailing edge;
• attaching a second strip member to the suction side shell member along the trailing edge of the blade such that a span-wise section of the second tape member defines an extension section that extends chord-wise beyond the trailing edge;
• adhesively attaching the respective extension sections of the first and second strip members together such that outboard edges of the extension sections define a bonded closure edge;
• finishing the bonded closure edge to achieve a desired outboard edge contour along the edge extension;
• and
• wherein the finishing comprises trimming a portion of the extension sections.
