Abstract

A blade for a wind turbine generally comprises a shell and a spar supporting at least a portion of the shell. The blade also includes first and second supports coupled to the spar and a damping element coupled to the first and second supports so as to be offset from the spar. The damping element is configured to counteract movement between the first and second supports caused by bending along the length of spar.
