Abstract: The present disclosure relates to methods (400, 500) for reducing vibrations in parked wind turbines (10), assemblies (82) comprising vibration mitigating devices (300) for wind turbine blades (22) and wind turbines (10). An assembly (82) comprises a vibration mitigating device (300) configured to be arranged around a wind turbine blade (22) of a wind turbine (10) and comprising one or more inflatable bodies (305) and one or more air flow modifying elements (310); and a pressure source (98) configured to inflate and/or deflate one or more of the one or more inflatable bodies (305) based on measurements of a sensor system (97) configured to monitor the wind turbine (10) and/or environmental conditions around the wind turbine (10).

Abstract: Disclosed is a wind turbine blade and a method for its production. The wind turbine blade comprises an upwind side shell part and a downwind side shell part. The upwind side shell part and the downwind side part are bonded together along at least one joint. At said at least one joint, the upwind side shall part and the downwind side shell part are bonded at an internal glue flange as well as at an external glue flange. The glue flange can be produced by using a mould insert along which the glue flange is laminated.
