Description

Windräder, welche z. B. beim Antrieb von Kolbenpumpen ein großes Anzugsmoment aufweisen müssen, baut man in der Regel als Windrad mit vielen Flügeln aus einfachem, gewölbtem Blech. Das große Anzugsmoment erreicht man dadurch, daß man dem Flügel bis außen hin eine große Breite bei entsprechender Winkelstellung zur Windrichtung gibt. Solche Windräder haben den Nachteil, daß sie keine sehr große Umfangsgeschwindigkeit im Verhältnis zur Windgeschwindigkeit erreichen, und daß ihr Wirkungsgrad infolge starker Wirbelbildung an den äußeren Flügelenden nur gering ist. Diese Wirbelbildung verursacht ein starkes Rauschen des laufenden Windrades' und hemmt bei größerer Umfangsgeschwindigkeit den Lauf des Rades ganz erheblich.Wind turbines, which z. B. a large torque when driving piston pumps must have, it is usually built as a wind turbine with many blades from simple, curved sheet metal. The large tightening torque is achieved by the wing up to the outside a large width with a corresponding angular position to the wind direction gives. Such wind turbines have the disadvantage that they do not have a very high peripheral speed in relation to the wind speed, and that their efficiency as a result strong vortex formation at the outer wing tips is only slight. This vortex formation causes a strong noise of the running wind turbine and inhibits larger ones Circumferential speed the running of the wheel quite considerably.

Die vorliegende Erfindung bringt eine wesentliche Verbesserung solcher Windräder mit vielen Flügeln. Ein bedeutend höherer Wirkungsgrad wird dadurch erreicht, daß die Flügel des Windrades an ihren Enden zugespitzt sind, und in einer kleinen Abrundung oder Spitze auslaufen.The present invention brings about a substantial improvement in such Wind turbines with many blades. A significantly higher degree of efficiency is achieved by that the blades of the wind turbine are pointed at their ends, and in a small one Rounding or tip tapering off.

Die Drehzahl im Verhältnis zur Windgeschwindigkeit wird trotz Beibehaltung der gleichen Winkelstellungen, wie sie beim Windrad üblich sind, erheblich größer. Dementsprechend kann man dem Getriebe eine größere Übersetzung geben und man erreicht so, trotz geringerer Flügelfläche, ein noch größeres Anzugsmoment und eine bedeutend größere Leistung als mit einem gleich großen Windrad der bekannten Bauart.The speed in relation to the wind speed is maintained despite the same the same angular positions as are usual with the wind turbine, considerably larger. Accordingly, you can give the transmission a larger translation and you can achieve so, despite the smaller wing area, an even greater tightening torque and a significant one greater performance than with a similarly sized wind turbine of the known type.

Die Abb. t zeigt die verschiedenen Flügelformen: a ist die bisher gebräuchliche Flügelform von vorn gesehen, b und c zeigen Flügelformen gemäß der Erfindung. Der Flügel b endigt in einer Spitze, c in einer kleinen Abrundung. Beide sind geeignet, die Wirbelbildung am Umfang des Windrades auf ein Mindestmaß herabzusetzen.Fig. T shows the different wing shapes: a is the one up to now Common wing shape seen from the front, b and c show wing shapes according to FIG Invention. The wing b ends in a point, c in a small rounding. Both are suitable for reducing the formation of eddies on the circumference of the wind turbine to a minimum.

Die Abb. 2 zeigt das vollständige Windrad von vorn gesehen. Es besteht aus einer Nabe, den Speichen und zwei Ringen, die zusammen das Rad als Traggerüst für die Flügelblätter des Windrades bilden.Fig. 2 shows the complete wind turbine seen from the front. It exists from a hub, the spokes and two rings that together form the wheel as a supporting structure for the blades of the wind turbine.
