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： In one aspect, a method for aligning a component into a wind direction is provided. The component comprises a sensor which is located such that at least part of the sensor is exposed to the wind. A signal is measured based on the force acting on the sensor due to the wind, and the component is rotated depending on the measured signal. Additionally a sensor for determining misalignment of a component relative to a wind direction is provided. The sensor comprises at least one flat element and at least one tool or device for measuring the force acting on the flat element.
