  • Publication number: 20140294591
    Abstract: A wind turbine blade has upper and lower shell members with a respective spar cap configured on an internal face of the shell members. A shear web extends between the spar caps along a longitudinal length of the blade. A connection assembly is configured between the transverse ends of the shear web and the spar caps and includes a channel structure configured on the spar cap. The channel structure includes side walls that extend from the spar cap along the longitudinal sides of the shear web. A pliant actuation line is attached between the side walls of the channel structure and bond paste is deposited in the channel structure. Movement of the transverse end of the shear web into the channel structure results in the actuation line pulling the side walls of the channel structure against the longitudinal sides of the shear web.

  • Publication number: 20130272892
    Abstract: A rotor blade assembly for a wind turbine is 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 a mounting plate and a noise reducer. The mounting plate is configured on a surface of the rotor blade. The noise reducer may include a base plate and a plurality of noise reduction features. The base plate is mounted to the mounting plate. The plurality of noise reduction features extend from the base plate.
