    Abstract: Disclosed is a wind turbine blade and a method for its manufacture. A lower shell part and an upper shell part are provided, each shell part having a leading edge end and a trailing edge end. A flatback profile component and web for connecting an inner surface of the lower side shell part with an inner surface of the upper side shell part are connected. The assembly which comprises the flatback profile component and the at least one web are placed on the lower shell part and the upper shell part is mounted. The wind turbine blade comprises a flatback profile component being arranged at the trailing edge, wherein the flatback profile component is coupled by at least one distance holder with at least one web, wherein the web couples the interior surface of the upwind side shell part with the interior surface of the downwind side shell part.

    Abstract: Disclosed is a wind turbine blade extending from a root end to a tip end, the wind turbine blade comprising a root region, and an airfoil region comprising the tip, a pressure side, a suction side and a chord extending between a leading edge and a trailing edge. The wind turbine blade comprises a leading edge protection element at the leading edge of the wind turbine blade. The leading edge protection element extends in a longitudinal direction between an outboard end and an inboard end and comprises a first section extending from the outboard end to a first section position, wherein the first section is made of a first erosion protection material having a first erosion resistance, and a second section extending from the first section position to a second section position, wherein the second section is made of a second erosion protective material having a second erosion resistance. The first erosion resistance is larger than the second erosion resistance.
