Abstract: A method of forming a wind turbine blade is provided which includes upper and lower blade mold halves, and a shear web having at least one aperture formed therein. A plurality of bulkheads are attached to the shear web and the shear web can be lifted and rotated, without need for a complex gantry/galactica apparatus, to be placed inside the lower blade mold. The upper mold half can then be closed with the shear web and bulkhead(s) disposed within the blade interior. A heating fluid can be pumped into the interior to pass through the bulkheads, circulating around the shear web and exiting the blade root with the assistance of a sump to pull the cold air outside the blade.

Abstract: Devices, systems, and methods of manufacturing wind turbine root attachment are provided. In various embodiments, an assembly for wind turbine root attachments includes a bushing, a core, and a filler. The bushing includes a body having cutouts extending from the proximal end to the distal end on either side of the bushing and a core cutout at the distal end. The bushing further includes an ear disposed at the proximal end of the bushing and within the first cutout. The core includes two wedges where the thick end of each wedge abut one another. The thin end of the proximal wedge is disposed within the core cutout and the core includes cutouts extending from the proximal end to the distal end on either side of the core. The filler is disposed within the cutout on the side of the assembly having the ear.

Abstract: Devices, systems, and methods for modular molding of wind turbine blades are provided. Methods of molding wind turbine blades using a modular molding assembly or system and methods of substituting molds are provided. In some embodiments, a modular assembly includes a first base frame and a second base frame hingedly coupled to one another, a first tooling frame disposed on the first base frame, a second tooling frame disposed on the second base frame, a first shell mold coupled to the first tooling frame, and a second shell mold coupled to the second tooling frame. The first shell mold has a first mold surface and a first perimeter and the second shell mold has a second mold surface and a second perimeter. When in an open configuration, the first base frame is coplanar with the second base frame, and, in a closed configuration, the first perimeter contacts the second perimeter.

Abstract: Devices, systems, and methods of improving heat transfer between a composite wind turbine blade surface are provided to reduce cure time. The assembly includes molds having heating wires disposed proximate the mold surface for delivering heat to the composite blade during layup and/or resin cure. Additionally, the vacuum bag disposed on top of the composite part includes a plurality of fluid channels for distributing a thermal fluid (e.g. heated/cooled water, air or oil) across the composite surface (opposite the mold surface).

Abstract: Devices, systems, and methods of improving manufacture of a composite wind turbine blade are provided to reduce cure time, and minimize consumable waste. After layup of a plurality of fiber panels along a blade mold, a pre-kitted vacuum bag can unrolled and overlaid on top of the fabric panels. The vacuum bag includes a plurality of fluid channels within the bag which have a pre-formed spring element embedded therein to allow for distribution a flowable resin to permeate the fiber panels and form a fiber-reinforced structural component, e.g. wind turbine blade.
