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.
