<p>A rotor blade for a wind power installation comprises a plurality of holes which are arranged in the region of the rotor blade root and which are in the form of through holes which extend substantially transversely with respect to the longitudinal axis of the rotor blade. Transverse pins are fitted into the holes. The tension elements are connected to the transverse pins. In that arrangement the tension elements in the state of the art extend within the rotor blade root and thus weaken the material in that region. In order to eliminate those disadvantages by means of a structural simplification, the rotor blade according to the invention is characterized by tension elements extending outside the rotor blade root. In that respect the invention is based on the realization that in that way the region of the rotor blade root at the hub is admittedly altered in an aerodynamically disadvantageous fashion, but that does not have any detrimental influence on the acoustic characteristics and the other properties of the installation because that region of the rotor blade is either covered by the spinner or is disposed at least in the part of the rotor, which rotates most slowly.</p> |
