The present invention relates to a wind turbine and a method of operating a wind turbine. The wind turbine comprises at least one wind turbine blade having an inner blade section and an outer blade section separated by a pitch junction. A first sealing element is arranged over an air gap in the pitch junction at the pressure sides of the blade sections. At least one second sealing element is arranged at the suction side of at least one blade section. The first and second sealing elements acts as air barrier to prevent air leakage from the pressure side to the suction side when pitching the outer blade section equal to or less than a predetermined pitch angle. |
