    摘要： Devices, systems, and methods of improving paste flow during the manufacture of wind turbine blades are provided. When the first turbine blade half is aligned with the second turbine blade half, a gap is formed between the first shell and the bond cap. The assembly includes a first mold half corresponding to the first turbine blade half and a second mold half corresponding to the second turbine blade half. When the first mold is aligned with the second mold, a second gap is formed. A first barrier is disposed within the first gap and a second barrier disposed within the second gap thereby fluidly sealing a volume defined by the first gap and the second gap to direct adhesive paste flow along the blade span between the adjoining leading and trailing edges.

    摘要： A mold for forming a wind turbine blade comprising first and second mold surfaces including a flange portion having an opening therein, wherein the first and second mold surfaces are configured for relative movement therebetween from an open position to a closed position. The opening of the first flange portion is aligned with the opening of the second flange portion when in the closed position, and a first magnet is disposed within the opening in the opening of the first mold surface, and a second magnet is disposed within the opening of the second mold surface.

    摘要： 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.

    摘要： A system for fabrication of a wind turbine blade including a laser projection which identifies the dimensions for a plurality of layup segments; determines the sequence of layup segments within first and second sections of the mold, wherein the sequence of layup segments within the second section of the mold are synchronized with the layup segments within a first section of the mold. The system also includes a projection device visually depicting the boundaries of a plurality of layup segments onto the mold. This system automates fabrication of composite structures by setting a pace for each task and ensuring operators complete each task within the allotted period. The projection system and layup delivery mechanism can advance with respect the mold to ensure the pace is maintained and an overall product cycle time is adhered to.

    摘要： 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.
