Abstract

The wind wheel is designed so that the blade adjustable in its pitch angle, at the blade tip and in the region between hub and blade tip, respectively carries respectively a pair of rings. An alteration of the pitch angle of the blade, rotates the front ring compared to the rear ring. So that also the pitch angle of all blade segments fixed at the ring pairs are correspondingly altered. The blade segments have a cross section comparable with the carrying wing of an airplane. By means of the wind energy, the water is dissociated and hydrogen is obtained.

Description

Bei Windrädern ist jeweils nur ein Abschnitt des Flügels im optimalen Bereich. Mit der vorgestellten Erfindung wird eine größere Flügelfläche in diesem optimalen Bereich betrieben. Die Flügel des Windrades tragen zwei Ringpaare, eines an den Flügelspitzen und eines weiter innen. Ein Ring ist jeweils mit den Flügelvorderkanten und einer mit den Flügelhinterkanten beweglich verbunden. Wird der Anstellwinkel der Flügel verändert, so verschieben sich die vorderen Ringe gegen die hinteren Ringe. Zwischen diesen Ringen sind nun weitere Flügelsegmente ebenfalls beweglich angeordnet, so daß sich deren Anstellwinkel ebenso wie der der Flügel ändert.With wind turbines, only a section of the wing is in the optimal range. With the Invention presented will have a larger wing area in this optimal range operated. The blades of the wind turbine carry two pairs of rings, one at the tips of the wings and one further inside. One ring is each with the leading edge of the wing and one with the Wing trailing edges connected movably. If the angle of attack of the wing is changed, so the front rings move against the rear rings. Are between these rings now further wing segments are also movably arranged so that their angle of attack just like that of the wing changes.

Wenn der Querschnitt dieser Flügelsegmente dem eines Flugzeugtragflügels entspricht, so kann bei starkem Wind und einem Anstellwinkel von nahezu 90° durch den "Auftrieb" bei gleicher Drehzahl das Drehmoment erhöht werden.If the cross-section of these wing segments corresponds to that of an aircraft wing, then can with strong wind and a setting angle of almost 90 ° by the "buoyancy" the same speed, the torque can be increased.

Dies erlaubt den Einsatz solcher Windräder auf hoher See, wo starke Stürme häufiger auftreten. Die auf See gewonnene Energie sollte zur elektrolytischen Zerlegung von Wasser genutzt werden. Der Wasserstoff wird verflüssigt und kann so effektiv gespeichert und transportiert werden.This allows the use of such wind turbines on the high seas, where strong storms are more common occur. The energy gained at sea should be used for the electrolytic decomposition of water be used. The hydrogen is liquefied and can be stored and stored effectively be transported.

Claims

1. Wind turbine, characterized in that the adjustable in their wings on the wing tip and in the area between the hub and wing tip each wear a pair of rings, between which wing segments are attached.

2. The ring pairs, characterized in that a change in the angle of attack Wing twisted the front ring in relation to the rear ring and thus also the Rise angle of all wing segments attached to the ring pairs accordingly is changed.

3. wing segments, characterized in that they are the wing of an aircraft have a comparable cross-section.

4. Wind turbine, characterized in that water dissociates and by means of wind energy Hydrogen is obtained.
