Abstract: A system for manufacturing a blade component of a rotor blade of a wind turbine includes a blade mold of the rotor blade, at least one blade skin arranged atop the blade mold, and a computer numeric control (CNC) device comprising a printer head and a scanning device. The printer head is configured for printing and depositing a material onto the at least one blade skin to form the blade component. The scanning device includes a processor and a scanner communicatively coupled to the processor. The scanning device is for determining a profile of the at least one blade skin atop the blade mold as the blade component is being printed and deposited layer by layer such that the printer head is automatically adjusted to compensate for changes in the profile in at least one of a horizontal direction or a vertical direction due to at least one of thermal expansion of the blade mold, thickness variations of fibers of the at least one blade skin, movement of the at least one blade skin atop the blade mold, or material shrinkages on previous printed layers.

Abstract: A method for repairing or improving a lightning protection system of a rotor blade of a wind turbine having a blade root and a blade tip includes identifying a repair or improvement location in the lightning protection system of the rotor blade. The method includes removing one or more layers of material at the repair or improvement location that form part of a shell of the rotor blade so as to expose existing conductive material in the rotor blade. The method also includes placing a conductive layer of material atop the repair or improvement location such that a root-side edge of the conductive layer overlaps the existing conductive material. Moreover, the method includes electrically connecting the root-side edge of the conductive layer with the existing conductive material and a tip-side edge of the conductive layer of material with the blade tip. The method further includes covering the conductive layer with an outer covering.
