    摘要： A blade for a wind turbine generally comprises a shell body defined by first and second shells extending between a leading edge and a trailing edge, an inner spar supporting at least a portion of the shell body, and a damping element coupled to at least one of the shell body or inner spar. The damping element is configured to move relative to the shell body to dissipate vibrations of the blade, and has a greater degree of freedom in a flapwise direction between the first and second shells than in an edgewise direction between the leading and trailing edges.

    摘要： A blade comprises a lightweight core, a composite material disposed on the core, and a skin located on the composite material. The composite material comprises fibers incorporated into a thermoplastic resin matrix in the form of a prepreg sheet or wet layup. The rotor blade may also comprise a front edge member attached along at least a portion of a leading edge of the core, a rear edge member attached along at least a portion of a trailing edge of the core, and a skin located over the core, the front edge member, and the rear edge member. The rotor blade may also comprise a spar extending through the core along a longitudinal axis of the rotor blade, and a skin located over the core and the spar. The edge members and the spars may be fabricated from thermoplastic material.
