摘要： Wind turbine blade having a length L, an airfoil with a chord C, and a first Gurney flap attached to the pressure or the suction surface of the airfoil near the trailing edge of the wind turbine blade. The first Gurney flap extends along at least 50% of the length of the outer ⅓rd of the wind turbine blade. By mounting the Gurney flap to the outer portion of the blade, the lift of the outer portion of the blade can be increased or decreased depending on the conditions in which the wind turbine is operating.

摘要： Wind turbine blade comprising a lightning protection system, said lightning protection system comprising a first lightning receptor mounted near the tip of the blade and an electrical conductor electrically connecting the first lightning receptor and the base of the wind turbine blade. The lightning protection system further comprises a first aerodynamic fence attached to the wind turbine blade between the lightning receptor and the tip of the blade. In this way, a zone of smoother airflow is provided which makes a more effective target for lightning to strike, thereby avoiding damage to other parts of the blade.

摘要： A computer system suitable for estimating the expected change in annual energy production (AEP) of a wind turbine due to structural deterioration of blades of the wind turbine, said computer system being arranged to execute the following steps: loading a dataset representing estimated lift and drag curves at specific radial locations along the original blade of the wind turbine, building a baseline BEM model of the wind turbine based on said estimated lift and drag curves of the original blade and analysing the model to provide a baseline AEP estimation of the wind turbine with original blades, loading a dataset representing aerodynamic effects of identified structural deteriorations at specific radial locations along each of the blades of the wind turbine, using the dataset of aerodynamic effects to generate modified lift and drag curves at specific radial locations along each of the blades.
