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.

Semi-automated layup process for fabrication of wind turbine blades using laser projection system

A method to design the kits and layup the reinforcement layers and core using projection system, comprising a mold having a contoured surface; a layup projection generator which: defines a plurality of mold sections; identifies the dimensions and location for a plurality of layup segments. A model-based calibration method for alignment of laser projection system is provided in which mold features are drawn digitally, incorporated into the plug(s) which form the wind turbine blade mold, and transferred into the mold. The mold also includes reflective targets which are keyed to the molded geometry wherein their position is calculated from the 3D model. This method ensures the precision level required from projection system to effectively assist with fabrication of wind turbine blades. In this method, digital location of reflectors is utilized to compensate for the mold deformations.
