A recent patent application (Publication Number: US20240025138A1) outlines a method for fabricating composite structures, with a focus on wind turbine blades. The method involves using a mold equipped with magnetic anchors and optical markers, which are magnetically coupled to the anchors. An optical projector is used to project beams towards the markers, allowing for the identification of their location on the mold. The projector is then calibrated by comparing the predetermined virtual marker location with the identified physical marker location.

Furthermore, the method includes steps such as removing the optical markers, depositing layup segments within the mold, injecting resin, and positioning magnetic anchors at specific locations on the blade. The use of multiple optical markers and magnetic anchors, along with the ability to adjust the digital marker location based on physical marker location discrepancies, ensures precise fabrication of composite structures. The method also incorporates the use of lasers for projecting optical beams, with the flexibility for relative movement and simultaneous or serial beam projection. Additionally, the optical markers are removed from the blade surface before closing the mold, highlighting a systematic approach to composite structure fabrication.
