Abstract

If the setting angle of the blades is altered, a front ring slides against a rear ring and the setting angle is transferred onto all blade segments. An inner pair of rings is adjusted independently of an outer pair of rings. This means that the setting angle for the blade segments to be given optimum adjustment. Independent claims are also included for the following: (A) Pairs of rings for altering the setting angle; (B) and for blade segments allowing twisting up to 90[deg]; (C) and for a rings with a double curve to form an air-conducting system.

Description

Bei Windrädern ist jeweils nur ein Abschnitt des Flügels im optimalen Bereich. Mit der vorgestellten Erfindung wird ein Windrad beschrieben, welches die vom Rotor überstrichene Fläche optimal zur Energiegewinnung nutzt. Dazu werden zwischen zwei Ringpaaren weitere Flügelsegmente gespannt.at wind turbines is only a portion of the wing in the optimal range. With the presented invention, a wind turbine is described which the swept by the rotor area optimally used for energy production. These are between two pairs of rings further wing segments curious; excited.

Die Flügel des Windrades tragen ein Ringpaar an den Flügelspitzen. Das innere Ringpaar ist mit der Nabe verbunden. Ein Ring des äußeren Ringpaares ist mit den Flügelvorderkanten, einer mit den Flügelhinterkanten beweglich verbunden. Wird der Anstellwinkel der Flügel verändert, so verschiebt sich der vordere Ring gegen den hinteren Ring und dieser Anstellwinkel wird auf alle Flügelsegmente übertragen. Die Ringe des inneren Ringpaares, welches von der Nabe gehalten wird, sind ebenfalls gegeneinander verschiebbar. Diese Verschiebung erfolgt unabhängig von der Flügelstellung. Damit lässt sich der innere Anstellwinkel der Flügelsegmente unabhängig vom äußeren Anstellwinkel einstellen und für jede Windgeschwindigkeit kann der optimale Anstellwinkel gewählt werden. (1)The wings of the windmill carry a pair of rings at the wing tips. The inner ring pair is connected to the hub. A ring of the outer ring pair is movably connected to the wing leading edges, one with the wing trailing edges. If the angle of attack of the wings is changed, the front ring moves against the rear ring and this angle of attack is transmitted to all wing segments. The rings of the inner ring pair, which is held by the hub, are also mutually displaceable. This shift is independent of the sash position. Thus, the inner angle of attack of the wing segments can be adjusted independently of the outer angle and for each wind speed, the optimum angle can be selected. ( 1 )

Dies bedingt, dass die Flügelsegmente nicht starr sind, sondern sich verwinden lassen müssen. Eine mögliche Ausführung sind Flügelsegmente, die über zwei Seile gespannt werden, die das äußere Ringpaar mit dem inneren Ringpaar verbinden. Distanzstücke zwischen den Seilen können dem Flügelsegment einen aerodynamischen Querschnitt verleihen.This conditionally that the wing segments not rigid, but must let go. A possible execution are wing segments, the above two cables are stretched, which the outer pair of rings with the inner Join ring pair. spacers between the ropes can the wing segment give an aerodynamic cross section.

Werden die äußeren Ringe aus doppelt gekrümmtem Material gefertigt, so erreicht man eine hohe Formsteifigkeit und die Ringe bilden ein Leitsystem für die durchströmende Luft. (2) If the outer rings are made of doubly curved material, a high degree of rigidity is achieved and the rings form a guidance system for the air flowing through. ( 2 )
