Abstract: The invention relates to a method for the controlled and automatic tensioning of bolts pre-installed in a flange joint between a hub and a main shaft in a nacelle of a wind turbine as well as to a bolt tensioning system for such method. The method comprises arranging a fixture inside the nacelle and mounting a bolt tensioning tool to the fixture which is mounted movable in an axial direction and in a working area perpendicularly hereto. First the flange joint is rotated to position a first set of bolts within the working area of the bolt tensioning tool, and then the bolt tensioning tool is controlled alternately to move the tensioning tool into a position for tensioning a bolt and to tension the bolt, until all bolts of the first set of bolts have been tensioned. The rotation of the flange joint may be controlled by operating a rotation tool operably connected to the main shaft, gearbox, and/or generator.

Abstract: A wind turbine blade is provided comprising a main blade portion and a light detection and ranging (LIDAR) element. The main blade portion has a shell defining an outer aerodynamic surface of the blade. The LIDAR element is disposed within a volume bounded by the outer aerodynamic surface and comprises at least one LIDAR system configured to transmit light beams away from the blade and to detect reflected light beams incident upon the blade.
