  • Patent number: 11614077
    Abstract: Provided is a wind turbine blade for a wind turbine, the wind turbine blade including: a first element containing carbon fibers, the first element being enclosed by a first metallic cover so as to form a Faraday cage around the same; a second element containing carbon fibers, the second element being enclosed by a second metallic cover so as to form a Faraday cage around the same; and an electrical bond connecting the first metallic cover and the second metallic cover. Elements containing carbon fibers are protected against lightning strikes allowing that such elements are placed further towards the tip, thereby making the whole blade lighter and allowing to better tailor the shape of the tip.
