Abstract
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.
