Abstract

Windrad mit einem ersten Profilrohr (13), wobei der Durchmesser des ersten Profilrohres (13) in Richtung der Luftströmung zuerst gleich bleibt (3), sich danach verkleinert (4), danach gleich bleibt (5), sich danach vergrößert (6) und danach wieder gleich bleibt (9), wobei sich im Inneren des ersten Profilrohres (13) ein zweites Profilrohr (12) befindet, mit einem anfangs gleichbleibenden Durchmesser (2), der sich danach aufteilt in einen sich vergrößernden Durchmesser (10) und in einen sich verkleinernden Durchmesser (7), der danach wieder gleich bleibt (8), wobei ein geschlossenes Profilrohr (11) zusammen mit dem zweiten Profilrohr (12) im ersten Profilrohr (13) so angebracht ist, dass eine Venturi-Düse entsteht, die die Luft am Rotor (1) abführt.Wind turbine with a first profile tube (13), wherein the diameter of the first profile tube (13) in the direction of air flow first remains the same (3), then reduced (4), then remains the same (5), then enlarged (6) and thereafter remains the same (9), wherein in the interior of the first profile tube (13) is a second profile tube (12), with an initially constant diameter (2), which then divides into an increasing diameter (10) and into one decreasing diameter (7), which thereafter remains the same (8), wherein a closed profile tube (11) together with the second profile tube (12) in the first profile tube (13) is mounted so that a Venturi nozzle is formed, which Air on the rotor (1) dissipates.

Description

Die Erfindung betrifft ein StaudruckThe invention relates to a dynamic pressure

Windrad,insbesondere zur Erzeugung von elektrischerWind turbine, in particular for generating electrical

Energie.Energy.

Windräder zur Erzeugung von elektrischer Energie werden sehr selten im privaten Bereich genutzt. Der Grund dafür liegt darin, dass die Windräder einen bestimmten Durchmesser und in einer bestimmten Höhe aufgestellt werden müssen, um wirtschaftlich elektrische Energie zu erzeugen.Wind turbines for the production of electrical energy are very rarely used in the private sector. The reason for this is that the windmills must be set up at a certain diameter and at a certain height in order to produce economic electrical energy.

Das Aufstellen von Windrädern auf Häuserdächern bedarf je nach Land und Gebiet einer Genehmigung des zuständigen Bauamtes.The erection of wind turbines on rooftops requires, depending on the country and territory of a permit from the relevant building authority.

Windräder zur Erzeugung von elektrischer Energie besitzen einen relativ kleinen Wirkungsgrad, weshalb entweder hohe Windgeschwindigkeiten oder große Durchmesser der Windräder notwendig sind um wirtschaftlich elektrische Energie zu erzeugen. Die heutigen Windräder nutzen nur einen kleinen Teil der kinetischen Energie aus dem Massenstrom der Luft.Wind turbines for generating electrical energy have a relatively low efficiency, which is why either high wind speeds or large diameters of the wind turbines are necessary to produce economic electrical energy. Today's wind turbines use only a small part of the kinetic energy from the mass flow of air.

Luftverwirbelungen an bzw. in der Nähe der Rotoren eines Windrades, können eine bremsende Wirkung auf das Windrad haben und somit auch die Effizienz der Stromerzeugung reduzieren.Air turbulence at or near the rotors of a windmill may have a braking effect on the windmill and thus also reduce the efficiency of power generation.

Der Erfindung liegt demnach die Aufgabe zugrunde, eine Windkraftanlage zur Erzeugung von elektrischer Energie so zu verbessern, dass oben erwähnte Nachteile nicht zum Tragen kommen.The invention is therefore based on the object to improve a wind turbine for generating electrical energy so that the above-mentioned disadvantages do not come to fruition.

Dies wird erfindungsgemäß durch die kennzeichnenden Merkmale der Ansprüche erreicht.This is inventively achieved by the characterizing features of the claims.

Fig. 1 zeigt den prinzipiellen Aufbau des Staudruck Windrades.Fig. 1 shows the basic structure of the dynamic pressure wind turbine.
