Abstract: Examples are generally directed to techniques for controlling a temperature of a blade in a wind turbine system. One example of the present disclosure is a method of controlling a temperature of a blade in a wind turbine system. The method includes setting a target temperature, inputting physical conditions of the blade and ambient conditions about the blade into a processor, outputting a minimum amount of energy to a heating element of the blade required to reach the target temperature based on the physical conditions and ambient conditions, and adjusting the energy provided to the heating element to reach the target temperature.

Abstract: A method of repairing erosion on a wind turbine blade while on a wind turbine includes placing a scanning device on an erosion zone. The device scans the erosion zone to gather an image and/or digital data. A printing system deposits a material according to the image and/or digital data. The repair system may include a frame such that scanning and/or depositing are with respect to the frame. A processing system interprets the image and/or digital data and produces an instruction file. Depositing the material may include depositing the material according to the instruction file. An unmanned aerial vehicle may be operated to position at least one of the scanning device and the printing system on the wind turbine blade. Alternatively, a rope/wire system may be operated to lower at least one of the scanning device and the printing system along the wind turbine blade.
