    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 method for determining the deflection and/or strain of an elongated member of a component is provided, in which a first point and a second point are assigned to the same side of an elongated member of the component, wherein the deflection and/or strain of the elongated member is determined by determining the distance between the second point and a third point, which is connected to the first point by an inflexible support, whereby the distance between the first point and the third point is considerably longer than the distance between the second point and the third point, and wherein the distance between the second point and the third point is determined in time steps and the frequency of the change of the distance is analyzed to detect frequency changes. Furthermore, an elongated member of a component subject to strain and comprises a sensor unit for determining the deflection and/or strain of the elongated member.
