Description

Strömungsrezeptoren im allgemeinen werden bei Windrädern, Wasserrädern oder Turbinen eingesetzt. (z. B. Quelle „Stromthemen", IZE EV, Postfach 700561, Frankfurt 70, 8. Jahrgang, Nr. 2, Seite 1 oben und Seite 2 ). Windräder mit horizontal laufenden Strömungsrezeptoren werden als „Darrieus-Rotoren" bezeichnet.Flow receptors in general are used in wind turbines, water wheels or turbines. (eg Source "Stromthemen", IZE EV, PO Box 700561, Frankfurt 70, Volume 8, No. 2, page 1 above and page 2 ). Wind turbines with horizontal flow receptors are referred to as "Darrieus rotors".

Strömungsrezeptoren mit Vorflügeln auch in der Anwendung als Horizontalläufer sind bekannt (Patentschrift DE 4120908 C2 aus 1989), wobei die Rezeptorflächen in der in jener Patentschrift vorgestellten Version stets entweder blattförmig flach oder als asymmetrisches Tragflächenprofil ausgebildet sind. Dies ist nicht effektiv, da das bewegte System im Falle blattförmig flacher Flächen keinerlei aerodynamisch bedingten Vortrieb erhält und im Falle asymmetrischer Flächen eine starke, zentrifugalkraftverstärkende Komponente auftritt, die Lager und Aufhängungen des Darrieus-Rotors stark belasten.Flow receptors with slats also in the application as horizontal runners are known (Patent DE 4120908 C2 from 1989), the receptor surfaces in the version presented in that patent always being either flat or asymmetrical in shape. This is not effective because the moving system in the case of sheet-like flat surfaces receives no aerodynamic propulsion and in the case of asymmetric surfaces a strong, centrifugal force-enhancing component occurs, the bearings and suspensions of the Darrieus rotor load heavily.

Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst:
Durch die Erfindung weist der Darrieus-Rotor keinen Leerlaufwinkel auf, da in jeder Stellung eine der Rezeptorflächen entweder durch aerodynamische Anströmung des symmetrischen Profils, oder durch Staudruckwirkung am Vorflügel in Vorwärtsbewegung versetzt wird.This problem is solved with the features listed in the protection claim 1:
By the invention, the Darrieus rotor has no idle angle, since in each position one of the receptor surfaces is offset either by aerodynamic flow of the symmetrical profile, or by dynamic pressure effect on the slat in forward movement.

Durch die Gleichheit der Strömungsgeschwindigkeit an Ober- und Unterseite des profilsymmetrischen Hauptflügels (2) tritt keine zentrifugalkraftverstärkende Kraft aufDue to the equality of the flow velocity at the top and bottom of the profile-symmetrical main wing ( 2 ), no centrifugal force enhancing force occurs

Im Gegensatz zu bisherigen Lösungen kombiniert die Erfindung die Vorteile von Darrieus-Rotoren (aerodynamisches Laufprinzip) mit denen eines Widerstandsläufers durch direkten Staudruck.in the Unlike previous solutions, the invention combines the advantages of Darrieus rotors (aerodynamic running principle) with those of a resistance runner by direct dynamic pressure.

Durch die Erfindung wird die Anlaufgeschwindigkeit merklich gesenkt, das System setzt sich schon bei wesentlich geringeren Windgeschwindigkeiten in Bewegung, als dies ohne Vorflügelkombination der Fall wäre.By the invention significantly reduces the start-up speed, the System already sits down at much lower wind speeds in motion, as this is the case without a vane combination would.

Die Erfindung kann in jeder beliebigen Anzahl (1 mit Gegengewicht, 2, 3 etc.) in horizontal laufenden Wind- oder Wasserrädern verbaut werden.The Invention can be used in any number (1 with counterweight, 2, 3 etc.) in horizontally running wind or water wheels be installed.

Eine Ausgestaltung der Erfindung wird in Zeichnung 1 erläutert. Es zeigt:

  • 1. Den Vorflügel
  • 2. Das symmetrische Flächenprofil
An embodiment of the invention will be explained in drawing 1. It shows:
  • 1 , The slat
  • 2 , The symmetrical surface profile

Mit Hilfe einer geeigneten Aufhängung (Bild 1/1) werden sowohl das Hauptprofil wie der Vorflügel starr zueinander mit festen Abständen montiert.With the help of a suitable suspension (Fig. 1 / 1 ) Both the main profile as the slat are mounted rigidly to each other with fixed distances.

Die Wirkung wird in Zeichnung 2 erläutert. Sie zeigt:

  • 3. Die Vortriebskomponente durch aerodynamische Anströmkraft
  • 4. Die Vortriebskomponente durch Staudruckwirkung
  • 5. Die Windrichtung
The effect is explained in drawing 2. She shows:
  • 3 , The propulsion component by aerodynamic approach force
  • 4 , The propulsion component by dynamic pressure effect
  • 5 , The wind direction
