20090146433 | Method and apparatus for fabricating wind turbine components - A method of assembling a wind turbine blade includes forming a preform pressure surface member and a preform suction surface member. The method also includes forming at least one of a leading edge and a trailing edge. One method of forming the leading edge or the trailing edge includes coupling a preform cap member to one of a portion of the preform pressure surface member and a portion of the preform suction surface member. At least a portion of one of the preform pressure surface member and the preform suction surface member overlap at least a portion of the preform bond cap member. Another method of forming the leading edge or the trailing edge includes coupling the preform pressure surface member to the preform suction surface member wherein at least a portion of the preform pressure surface member overlaps at least a portion of the preform suction surface member. | 06-11-2009 |
20110142660 | WIND TURBINE BLADE WITH INTEGRATED HANDLING MECHANISM ATTACHMENT BORES - A wind turbine blade includes a leading edge, a trailing edge, a suction side, and a pressure side. At least one integrated attachment bore is configured in each of the suction side and pressure side between the leading edge and trailing edge. The attachment bores are structurally configured for receipt of a handling mechanism therein for supporting the blade during a transportation, installation, or maintenance procedure. | 06-16-2011 |
20120040106 | APPARATUS FOR IMPREGNATING A FIBER MATERIAL WITH A RESIN AND METHODS FOR FORMING A FIBER-REINFORCED PLASTIC PART - A method for forming a fiber-reinforced plastic part is provided. The method includes providing a mold, providing a vibration generator, placing a fiber material in the mold, infusing the fiber material with a resin while the fiber material and/or the resin are exposed to vibrations, and curing the resin. | 02-16-2012 |
20140072440 | ATTACHMENT SYSTEM FOR A WIND TURBINE ROTOR BLADE ACCESSORY - A rotor blade assembly for a wind turbine has a rotor blade. A strip-member blade accessory is mounted to one of the rotor blade surfaces that stretches under normal operating conditions of the wind turbine. The blade accessory has a base portion. An attachment layer connects the base portion to the rotor blade surface and has a lower shear modulus than the base portion to allow for shear slippage between the base portion and the underlying rotor blade surface. | 03-13-2014 |
