Abstract

The wind-turbine has vertical double axle, a smaller vertical turbine (7), placed in the center of a vertical outer turbine (6), rotating freely around a vertical axis (9).

Description

Bei der technischen Nutzung von Windenergie werden zwei unterschiedliche Rotorsysteme verwendet, unterteilt nach Lage der Rotorachsen.at The technical use of wind energy will be two different Rotor systems used, subdivided according to position of the rotor axes.

Es gibt Rotore mit horizontalen Achsen und Rotore mit vertikalen Achsen.It There are rotors with horizontal axes and rotors with vertical axes.

Horizontalachsen-Rotore müssen in den Wind gestellt werden, was bei häufig wechselnder Windrichtung hohen technischen Aufwand bedingt.Horizontal axis rotors have to be put into the wind, which often changes the wind direction high technical complexity.

Bei Vertikalachsen-Rotoren gibt es mehrere unterschiedliche Systeme:

  • 1. Savonius-Rotor. Dieses System hat zwei ineinandergreifende Halbschalen. (1)
  • 2. Darrieus-Rotor. Dieses System hat senkrechte schmale gebogene Flügelblätter. (2)
Vertical axis rotors have several different systems:
  • 1. Savonius rotor. This system has two interlocking half shells. ( 1 )
  • 2. Darrieus rotor. This system has vertical narrow curved blades. ( 2 )

Im Internet sind noch eine Reihe anderer Systeme dargestellt, von denen eines besonders beachtenswert erscheint: es ist der H-Rotor. (3) An waagerechten Trägerflügeln sind die senkrechten Rotorflügel befestigt.There are a number of other systems on the Internet, one of which is particularly noteworthy: it is the H rotor. ( 3 ) The vertical rotor blades are fastened to horizontal support wings.

Wenn diese Art Rotor viele senkrechte Flügel besitzt, die nahezu den gesamten Umfang des Rotors abdecken (4) ergibt sich das Bild eines senkrecht stehenden Zylinders, der von Schlitzen unterbrochen ist. Für Kleinanlagen etwa bis 5 m Durchmesser ist dieses System leicht zu realisieren. Auf der Windenergieausstellung in Hamburg am 16.-19.5.06 stellte ein japanischer Hersteller eine vierflüglige Anlage vor. Auf diese Anlage wird als Stand der Technik Bezug genommen. (5) Grundsätzlicher Nachteil der Vertikalachsen-Rotore ist zur Zeit gegenüber den Horizontalachsen-Rotoren der schlechtere Wirkungsgrad. Ursache dafür ist der teilweise Strömungsabriß der dem Wind gegenläufigen Rotorseite. Bei Kleinanlagen erscheint die Flügelblattverstellung technisch zu aufwändig, das heißt zu kostspielig. Eine hierfür gedachte Lösung des vorgenannten Problems wird durch die in dem Anspruch genannte und nachfolgend beschriebene Mechanik erreicht.If this type of rotor has many vertical wings that cover almost the entire circumference of the rotor ( 4 ) results in the image of a vertical cylinder interrupted by slots. For small systems up to 5 m in diameter, this system is easy to implement. At the wind energy exhibition in Hamburg on 16.-19.5.06 a Japanese manufacturer presented a four-winged plant. This plant is referred to as the prior art. ( 5 ) Fundamental disadvantage of the vertical axis rotors is currently compared to the horizontal axis rotors of the worse efficiency. The reason for this is the partial stall of the rotor side opposite the wind. For small systems, the blade adjustment seems technically too complex, that is too expensive. A solution of the aforementioned problem intended for this purpose is achieved by the mechanism mentioned in the claim and described below.

Beschreibung des Baumusters, (6):Description of the model, ( 6 ):

In die Mitte einer vielflügeligen Vertikalturbine (6) wird eine kleinere Vertikalturbine (7) so eingesetzt, dass sie sich frei auf der Vertikalachse innerhalb der größeren Turbine drehen kann. Weil die kleine mittige Vertikalturbine eine höhere gleichsinnige Drehzahl hat als die Außenturbine, die mit dem Antrieb der Nutzgeräte belastet und dadurch abgebremst wird, werden die Strömungsabrisse besonders an den Flügelinnenseiten (8) der Außenturbine verhindert. Die Begründung: Die Grenzschicht um die Flügel der Innenturbine gerät in eine gleichsinnige Drehbewegung der Turbinen-Drehrichtung und transportiert dadurch einen Teil des Luftstroms an die Rückseite der dem Wind gegenläufigen Flügel der Außenturbine.In the middle of a multi-bladed vertical turbine ( 6 ), a smaller vertical turbine ( 7 ) so that it can rotate freely on the vertical axis within the larger turbine. Because the small central vertical turbine has a higher speed in the same direction as the outer turbine, which is charged with the drive of the Nutzgeräte and thereby slowed down, the stalls are particularly on the wing inside ( 8th ) prevents the outer turbine. The reason: The boundary layer around the wings of the inner turbine gets into a rotational movement in the same direction of the turbine rotation direction and thereby transported a portion of the air flow to the back of the wind opposite the wing of the outer turbine.
