The invention relates to a large-scale wind power installation. While rotor blades that are optimized to provide for maximum output can be easily produc ed for smaller installations and can be transported without problems, rotor blades for larger installations have two draw-backs. The very large surface of the rotor blade produces very high loads on the rotor blade base at high win d speeds so that the power installation has to be switched off. These very hig h loads require a specific design (dimensioning) of the entire wind power installation. The second draw-back resides in the production of a rotor blad e with a very large blade depth. The aim of the invention is to overcome these problems and to simplify both the production and the operation of the wind power installation. To this end, the wind power installation is provided wit h at least two rotors in tandem, the first rotor that is disposed in front of the second rotor having a smaller diameter than the second rotor. |
