Abstract

The wind generator is esp. for the utilisation of sideways directed gusts of wind. It consists of a wind vane (A) with a rubber (B) freely suspended from the vane end away from the wind. The wind oscillates vane and rudder at a frequency, which is at a certain ratio to the mass of the whole system. Several generators may be positioned behind each other, at certain angles, to utilise the induced frequency. The generator may also be used in flowing water.

Description

Windgenerator Es gibt zur Ausnutzung der Windenergie Windgeneratoren, die auf dem Prinzip eines Windrades beruhen. Wind generator There are wind generators to utilize wind energy, which are based on the principle of a wind turbine.

Ein Windrad nutzt die frontale Windbewegung aus.A wind turbine uses the frontal wind movement.

Neben der frontalen Windbewegung besteht die Windenergie aber auch aus dem sogenannten Bölenspektrum, d.h. der Bewegung, die der Wind in seitlicher Richtung ausführt. Berechnungen dieser Bewegung führen zur Erkenntnis, daß die seitliche Bewegung etwa 20 bis 40 % der Bewegungsenergie des gesamten Luftstromes beinhaltet. Das bedeutet, daß man den Wirkungsgrad eines herkömmlichen Windrades beträchtlich steigern kann, wenn man die seitliche Strömung ebenfalls erfaßt.In addition to the frontal wind movement, there is also wind energy from the so-called böl spectrum, i.e. the movement that the wind in sideways Direction executes. Calculations of this movement lead to the knowledge that the lateral Movement contains about 20 to 40% of the kinetic energy of the entire air flow. This means that the efficiency of a conventional wind turbine is considerable can increase if the lateral flow is also recorded.

Der erfindungsgemäße Windgenerator erreicht das in folgend beschriebener Weise: Eine Windfahne A trägt an seinem der Windrichtung abgewendeten Ende ein Ruder B, das freischwingend aufgehängt ist. Die Windfahne A und das Ruder B beginnt bei Wind in einer in bestimmten Verhältnis zur Masse des gesamten Systems stehendenden Frequenz zu schwingen. Es entsteht infolge der frontalen Strömung, da das Ruder B von einer Seite auf die andere Seite schwingt, wechselseitiger Unter- und ueberdruck, der bei einem Flugzeug-Tragflügel z.B. den Auftrieb bewirkt. Bei dem erfindungsgemäßen Windgenerator jedoch ein seitliches Hin- und Herschwingen verursaaht.The wind generator according to the invention achieves that which is described below Way: A wind vane A carries a rudder at its end facing away from the wind direction B, which is freely suspended. The wind vane A and the rudder B start at Wind in a certain proportion to the mass of the entire system Frequency to oscillate. It arises as a result of the frontal current, as the rudder B swings from one side to the other, alternating negative and positive pressure, which e.g. causes the lift in an airplane wing. In the inventive However, the wind generator causes it to swing back and forth to the side.

Verstärkt wird diese Strömung durch die seitliche Luftbewegung, die sich aus dem Böenspektrum der natürlichen Windbewegung zusammensetzt und dem Abwind eines erfindungsgemäßen Windgenerators der gemäß eines Mach'chen Strömungswinkels hinter einem vorderenWindgenerator angeordnet ist. Eine derartige Windfahnen-Batterie nutzt den Wind optimal aus. Der Wirkungsgrad ist gegenüber einem Windrad größer. Die Frequenz läßt sich steuernd beeinflussen. Der Aufwand zum Bau ist kleiner wie bei einem Windrad.This flow is reinforced by the sideways air movement that is composed of the gust spectrum of the natural wind movement and the downdraft of a wind generator according to the invention according to a Mach's flow angle is located behind a front wind generator. Such a wind vane battery makes optimal use of the wind. The efficiency is greater than that of a wind turbine. The frequency can be influenced in a controlling manner. The effort to build is less like at a wind turbine.
