Abstract: The present disclosure relates to dampening of predominantly edgewise vibrations in a wind turbine blade. This is achieved by a wind turbine blade comprising one or more bump airfoil sections, each bump airfoil section being characterised in that for any airfoil within the bump airfoil section, the airfoil's pressure side profile yp has particular geometric properties near the trailing edge of the airfoil. Furthermore, a total length of all bump airfoil sections in the blade is at most 30% of the length of the blade, and at least half of the total length of all bump airfoil sections in the wind turbine blade is provided by one or more bump airfoil sections located spanwise in the outermost 30% of the blade.

Abstract: A method for manufacturing a shell 36 and 38, is disclosed. The method includes laying one or more layers of fibres, on a surface of a mould 9 to form at least a portion of a shell half structure 36 and 38. A first panel 11 defined with noise reduction members 11a is positioned adjacent to the one or more layers of fibres on the surface of the mould 9. Further, resin is infused through the one or more layers of fiber and the first panel 11 and is subsequently cured to obtain the shell half structure 36 or 38, where the first panel 11 with noise reduction members 11a adheres to the shell half structure 36 and 38 upon curing the infused resin.
