  • Wind turbine blade comprising a trailing edge noise reducing device
    Patent number: 11473555
    Abstract: This invention relates to a noise reducing device, a wind turbine blade comprises such a noise reducing device, a method of retrofitted a noise reducing device, and a method of manufacturing such a noise reducing device. The noise reducing device comprises first noise reducing elements projecting from a base part having a third surface towards a second end. Second noise reducing elements are attached to the third surface and projects along the first noise reducing elements towards the second end. The first noise reducing elements are preferably serrations while the second noise reducing elements are bristles. The bristles projects at least into the gaps formed between adjacent serrations.
