  • Publication number: 20230184208
    Abstract: A wind turbine blade includes a leading edge protection element attached to the leading edge of the wind turbine blade. The leading edge protection element extends in a longitudinal direction between an outboard end and an inboard end and includes an attachment surface mounted to an exterior surface of the blade, an exterior surface opposite the attachment surface, a first section extending from the leading edge and along a part of the pressure side of the wind turbine blade to a first transverse end at a first position on the pressure side of the blade, and a second section extending from the leading edge and along a part of the suction side of the wind turbine blade to a second transverse end at a second position on the suction side of the blade.

  • Patent number: 9752444
    Abstract: An erosion shield for a wind turbine blade is described, the erosion shield having a plurality of layers of erosion resistant material. The layers of erosion resistant material have an adhesive bond strength between adjacent layers less than the cohesive tensile strength of the layers, such that the outer layers of erosion resistant material are arranged to peel away or delaminate from the erosion shield under the action of the wind once the particular layer is ruptured or eroded. This dynamic removal of the outer layers of the erosion shield provides for increased shield lifetime, and a reduction in the maintenance operations required for a wind turbine blade having such an erosion shield.

  • Patent number: 9610739
    Abstract: A repair solution for a wind turbine blade is described. The repair solution includes the application of a layer of viscous coating material to the section of the blade to be repaired, which is cured to form a repaired surface. The layer of viscous coating material may be temporarily covered during the curing process using a film of Low Surface Energy material, to prevent defects in the repaired surface from dust, insects, etc. Additionally or alternatively, a temporary shield may be erected adjacent the curing layer of coating material, to allow for the control of the temperature and/or humidity levels of the region adjacent the curing material, to provide for more effective control of the curing process and to allow for repairs to be carried out for a wider process window.
