Abstract

Wing profiles in a rotor frame are made to rotate by the incident wind flow and the lift thus generated. Conditions for rotational movement are met by periodic angular adjustment of the rotor blades, to give lift with positive pitch angles and downforce with negative pitch angles acting as rotational forces on the drive shaft. The span, number of rotor blades and the rotor diameter determine the power of the unit.

Titel: WINDTURBINE MIT WAAGERECHTER WELLETitle: WIND TURBINE WITH HORIZONTAL SHAFT

Stand der Technik: Die Nutzung der Windkraft zur Energiegewinnung wird derzeit wie folgt gelöst:State of the art: The use of wind power for energy generation is currently solved as follows:

Auf einem, als Beispiel angeführten Stahlrohrturm, der von der Erdoberfläche gemessen- je nach Größe der Anlage- zwischen 30 m bis 110 m beträgt, wird auf der oberen Turmfläche die Rotorwelle mit angeflanschtem Generator einerseits und anderseits die Rotornabe zur Aufnahme der Rotorblätter angebracht.On a tubular steel tower, given as an example and measured from the surface of the earth - depending on the size of the system - is between 30 m and 110 m, the rotor shaft with flange-mounted generator is attached to the upper tower surface on the one hand and the rotor hub for receiving the rotor blades on the other.

Die Form der Rotorblätter, die Befestigung, winkelverstellbar an einer Nabe ist aus aerodynamischer Betrachtung vergleichbar, mit dem Propeller eines Flugzeugs.The shape of the rotor blades, the fastening, adjustable in angle on a hub, is comparable from an aerodynamic point of view, with the propeller of an aircraft.

Die aerodynamischen Parameter kommen hier modifiziert auf Windgeschwindigkeiten von 4m/s bis 25m/s zur Anwendung. Zur Verbesserung der Windkraftnutzung werden bei herkömmlichen Windkraftanlagen bereits Rotordurchmesser bis zu 90 m eingesetzt. Trotz Blattwinkelverstellung und Einsatz leichter Werkstoffe für die Rotoren, ist die Nennleistung herkömmlicher Anlagen bei einer Windgeschwindigkeit von 4m/s, 70 kW und bei einer Windgeschwindigkeit von 25m/s, ist eine maximale Leistung ca. 2300 kW erreichbar. The aerodynamic parameters are used here modified for wind speeds from 4m / s to 25m / s. To improve wind power utilization, rotor diameters of up to 90 m are already used in conventional wind power plants. Despite the blade angle adjustment and the use of light materials for the rotors, the nominal power of conventional systems at a wind speed of 4m / s, 70 kW and at a wind speed of 25m / s, a maximum power of 2300 kW can be achieved.
