Vorrichtung zur Energiegewinnung aus Windkraft.Device for generating energy from wind power.

Stand der Technik:State of the art:

Die Nutzung der Windkraft zur Energiegewinnung wird derzeit wie folgt gelöst:The use of wind power to generate energy is currently solved as follows:

Auf einem Stahlrohrturm, der von der Erdoberfläche gemessen - je nach Größe der Anlage- zwischen 45 m und 110 m Höhe beträgt, wird auf der oberen Turmfläche die Rotorwelle mit angeflanschten Generator einerseits und andeseits die Rotornabe zur Aufnahme der Rotorblätter angebracht.
Die Form der Rotorblätter, die Befestigung an eine Nabe sind aus aerodynamischer Betrachtung vergleichbar, mit einem Propeller eines Flugzeuges. Die aerodynamischen Parameter kommen hier modifiziert auf geringere Strömungsgeschwindigkeiten zur Anwendung.On a tubular steel tower, which is between 45 m and 110 m high from the earth's surface - depending on the size of the plant - the rotor shaft with flanged generator is mounted on the upper surface of the tower on one side and the rotor hub for holding the rotor blades on the other side.
From an aerodynamic point of view, the shape of the rotor blades and the attachment to a hub are comparable to an aircraft propeller. The aerodynamic parameters are modified here to apply to lower flow speeds.

Zur Verbesserung Windkraftnutzung werden bei herkömmlichen Windkraftanlagen Rotordurchmesser bis zu 90 Meter verwendet. Trotz Blattwinkelverstellung und Einsatz leichter Werkstoffe für die Rotoren ist die Nennleistung herkömmlicher Anlagen bei einer Windgeschwindigkeit von 4m/s, 70,0 kW und bei einer Windgeschwindigkeit von 25m/s, eine maximale Leistung von 2300 kW erreichbar.To improve the use of wind power, conventional wind turbines use rotor diameters of up to 90 meters. Despite blade angle adjustment and the use of lightweight materials for the rotors, the nominal output of conventional turbines is 70.0 kW at a wind speed of 4 m/s and a maximum output of 2300 kW at a wind speed of 25 m/s.

Problem:Problem:

Lösung:Solution:

Erreichte Vorteile:Benefits achieved:

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, einen Rotor zu entwickeln, der über die gesamte Rotorlänge gleichgroße Auftriebswerte erzielt.The invention specified in claim 1 is based on the problem of developing a rotor which achieves uniform lift values over the entire rotor length.

Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmaien (horizontal, um die x-Achse rotierende Rotorblätter) gelöst.This problem is solved with the features listed in claim 1 (horizontal rotor blades rotating around the x-axis).

Mit der Erfindung wird erreicht, dass die erzielte Energieausbeute, im Vergleich zu herkömmlichen Anlagen, um das mehrfache ansteigt.The invention ensures that the energy yield achieved increases several times compared to conventional systems.
