The invention concerns a wind power installation, in particular a large-scale wind power installation with an output power of more than two MW, preferably about five MW or more In accordance with the invention, for a large-scale wind power installation of that kind, there is proposed a rotor design and the configuration of corresponding rotor blades, so that reliable operation of such a wind power installation is possible. While such a rotor blade which is optimised for a maximum degree of efficiency is good to produce for relatively small installations and can also be transported without any problem, such a rotor blade design suffers from two disadvantages. Firstly, the very large area of the rotor blade at the rotor blade root gives rise to very high loads when high wind speeds are involved. The wind power installation is usually then already shut down. However, the entire wind power installation has to be designed (dimensioned) for those very high loads. The second disadvantage lies in production of a rotor blade involving a very great blade depth. The object of the invention is to eliminate the above-indicated problems and to simplify the production of a wind power installation and the operation thereof. A wind power installation comprising at least two rotors which are arranged one behind the other and of which the first rotor which is arranged in front of the second rotor is of a smaller diameter than the second rotor.
La présente invention concerne une éolienne de grande envergure. Les pales de rotor optimisées pour un rendement maximal sont faciles à fabriquer pour de petites éoliennes et peuvent également être transportées sans problème, mais pour des éoliennes de grande envergure, les pales de rotor fabriquées selon un tel concept présentent deux inconvénients. Premièrement, la très grande surface de la pale de rotor entraîne de fortes charges sur le talon de pale en cas de vitesses du vent très élevées. Une grande éolienne est donc régulièrement arrêtée. En outre, l'éolienne dans son ensemble doit être conçue (dimensionnée) pour ces très fortes charges. Le second inconvénient concerne la fabrication d'une pale de rotor à très grande profondeur. L'objet de la présente invention est d'éliminer les problèmes susmentionnés et de simplifier la fabrication de l'éolienne ainsi que son fonctionnement. A cet effet, l'éolienne selon la présente invention possède deux rotors placés l'un derrière l'autre dont le premier, placé devant le second, possède un diamètre inférieur au second.
