| 20090087318 | WIND TURBINE SPARS WITH JOINTED SHEAR WEBS - A spar for a wind turbine blade includes at least one shear web extending between pressure and suction sides of the blade; and a joint, arranged substantially midway between ends of the shear web, for sizing the shear web. The joint may include a resilient and/or expandable spacer. | 04-02-2009 |
| 20100135814 | RETROFIT SLEEVE FOR WIND TURBINE BLADE - A wind turbine blade includes a body having a first surface characteristic; and a sleeve, arranged on the body, having a second surface characteristic which is different from the first surface characteristic. | 06-03-2010 |
| 20110162787 | RETROFIT SLEEVE FOR WIND TURBINE BLADE - A method of manufacturing a retrofit sleeve for a wind turbine blade, includes positioning at least a portion of a blade-shaped form in a mold; and applying a curable material to the space between the form and mold. | 07-07-2011 |

| 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 |

| 20080219851 | INTEGRATED SHEAR WEBS FOR WIND TURBINE BLADES - The present invention includes a method for fabricating elongated wind turbine blades and wind turbine blades formed by the method. The method includes providing a first shell reinforcing fiber structure. At least one shear web reinforcing fiber structure is positioned adjacent to the first shell reinforcing fiber structure. The method includes infusing the first shell reinforcing fiber structure and shear web reinforcing fiber structure with a matrix material and curing the matrix material to form a unitary composite first shell component. Thereafter a composite second shell component is attached to the composite first shell component to form an elongated composite airfoil suitable for use as a wind turbine blade. The wind turbine blades formed include unitary components providing reduced number of adhesive joints. | 09-11-2008 |
