    摘要： A wind turbine rotor blade is provided which includes a root end and a tip end located opposite the root end. A leading edge extends from the root end to the tip end. A trailing edge extends from the root end to the tip end. A span direction is defined by a line extending linearly from the root end to the tip end. A chord direction is perpendicular to the span direction and lies in the plane extending through the leading edge and the trailing edge. A shoulder is the point of the maximum chord-wise extension. An airfoil portion extends from the shoulder to the tip end. The airfoil portion comprises a span-wise interval begging before the tip end and extending to or close to the tip end and in which the distribution of the chord-wise extension is increased as compared to the load optimised distribution of the chord-wise extension.

    摘要： A wind turbine rotor blade defined by a tip point, a shoulder, a maximum chord interval which is defined as the radial interval over which the blade chord is no less that 95% of the shoulder chord and which extends over at least 15% of the entire blade length, and an outer blade interval extending from the maximum chord interval to the tip point, wherein the outer blade interval has a concave hyperbolic chord distribution from the maximum chord interval towards the tip point. Further a method for optimizing the chord distribution of a wind turbine blade layout is provided, wherein the chord distribution is optimized by optimizing the chord distribution in the maximum chord interval by maximizing the ratio of the annual energy production to the loads acting on the blade and in the outer blade interval with respect to the annual energy production alone.

    摘要： A wind turbine rotor blade with a suction side and a pressure side is provided. The blade includes a cylindrical root portion, an airfoil portion defining the suction side and the pressure side, and a transition portion which is located between the airfoil portion and the root portion. The transition portion has a transition profile changing from the airfoil of the airfoil portion to the cylindrical profile of the root portion. The leading section of the transition profile is cylindrical and the trailing section of the transition profile is elongated. In the rotor blade, the maximum chord length of the airfoil portion is at least the maximum chord length of the transition portion. In addition, the transition profile includes a section with a concave curvature on the pressure side of the rotor blade.
