Abstract: The present invention relates to a leading edge protection for a wind turbine blade, wherein a leading edge axis of the leading edge protection is configured to be fitted on at least part of a leading edge of a wind turbine blade and the leading edge protection is configured to extend between the leading edge and a first edge downstream a first side of the wind turbine blade as well as between the leading edge and a second edge downstream a second side of the wind turbine blade, wherein the leading edge protection comprises a first part and wherein the first edge is configured to be non-parallel with the leading edge of the wind turbine blade along the first part of the leading edge protection. The present invention further relates to a wind turbine blade comprising the leading edge protection and a wind turbine comprising the wind turbine blade. Finally, the present invention relates to a method for protecting a leading edge of a wind turbine blade arranged on a wind turbine and a leading edge protection obtainable by that method.

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.

Abstract: The present invention relates to method for estimating energy production (107) from a wind turbine (101) with plurality of blades (102). The method comprises obtaining one or more infrared images (103) of each blade (102) of the wind turbine (101). Further, identifying one or more cross-sectional regions (302) of each of the blade (102) using the one or more infrared images (103) based on a boundary region (301), wherein the boundary region (301) is indicating a transition from a laminar air flow to a turbulent air flow. Furthermore, determining plurality of polar values indicative of an aerodynamic profile for each of the one or more cross-sectional regions (302) based on one or more panel method based techniques and the boundary region (301). Finally, estimating the energy production (107) for the wind turbine (101) based on one or more blade (102)-element momentum (BEM) based techniques using the plurality of polar values.

Abstract: The present invention relates to a leading edge protection for a wind turbine blade, wherein a leading edge axis of the leading edge protection is configured to be fitted on at least part of a leading edge of a wind turbine blade and the leading edge protection is configured to extend between the leading edge and a first edge downstream a first side of the wind turbine blade as well as between the leading edge and a second edge downstream a second side of the wind turbine blade, wherein the leading edge protection comprises a first part and wherein the first edge is configured to be non-parallel with the leading edge of the wind turbine blade along the first part of the leading edge protection. The present invention further relates to a wind turbine blade comprising the leading edge protection and a wind turbine comprising the wind turbine blade. Finally, the present invention relates to a method for protecting a leading edge of a wind turbine blade arranged on a wind turbine and a leading edge protection obtainable by that method.
