摘要： 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.

摘要： The present disclosure relates to devices for wind turbine blades and methods for reducing vibrations in wind turbines with a rotor in standstill. A device comprises a portion configured to protrude beyond a leading edge of the wind turbine blade. A device comprising a portion configured to protrude beyond the leading edge of the wind turbine may be releasably attached around a wind turbine blade substantially along a chordwise direction. The device may be detached from the blade before the wind turbine starts to operate.

摘要： The present disclosure relates to devices for wind turbine blades and methods for reducing vibrations in wind turbines. More particularly, the present disclosure relates to devices for mitigating vortex induced vibrations and stall induced vibrations, wind turbine blades comprising such devices, and methods for reducing wind turbine vibrations when the wind turbine is parked, especially during wind turbine installation and/or maintenance. A method for mitigating vibrations of a parked wind turbine comprises arranging a device in an inactive state with a wind turbine blade; and causing the device to transition to an active state in which the device grips the wind turbine blade more strongly than in the inactive state.
