Propeller mit zwei Doppelflügeln Die Anlage zur Nutzung der Windenergie ( Abb. 1 ) be= sitzt zwei Flügel,von denen jeder wiederum aus zwei pa= rallelen und durch quer eingebaute Einlagen verstärkten Flügeln besteht.Diese Flügel sind entsprechend profiliert und sich gegenüber entsprechend situiert ( Abb. 2).Propeller with two double blades The system for using wind energy (Fig. 1) has two wings, each of which in turn consists of two parallel wings and wings reinforced by inserts built into the transverse direction appropriately profiled and positioned opposite each other accordingly (Fig. 2).

Diese Lösung ermöglicht bessere Nutzung der Windenergie im Vergleich zu den schon bestehenden Lösungen ,da auf diese Weise der Bau von Propellern mit großen Flügelflä= chen,jedoch ohne ihr Gewicht bedeutend zu vergrößern, möglich ist.This solution enables better use of wind energy in comparison to the already existing solutions, since in this way the construction of propellers with large wing areas, but without significantly increasing their weight is.

Dank dem Zusammenbauen von zwei Flügeln,die entsprechend profiliert und einander gegenüber situiert sind ( Abb. 2), erreichen wir eine sehr gute Aerodynamik und auf diese Weise eine vorteilhafte Verteilung der auf die Flügel wirkenden Kräfte.Thanks to the assembly of two wings that are appropriately profiled and are situated opposite each other (Fig. 2), we achieve very good aerodynamics and in this way an advantageous distribution of the forces acting on the wings.

Diese Anlage arbeitet,dank den speziellen Profilen der Flügel,selbst beim Abweichen des Windes bis zu 35 von der Achse des Propellers und ist so auf plötzlichen Richtungswechsel des Windes bis zu 70 unempfindlich.This system works by itself thanks to the special profiles of the wings when the wind deviates up to 35 from the axis of the propeller and is so on sudden change of direction of the wind up to 70 insensitive.

Die in den Punkten 2,3,4 angegebenen Eigenschaften bewir= ken,daß diese Windkraftanlage leistungsfähiger ist als die bisher gebauten Anlagen.The properties specified in points 2,3,4 have the effect that this wind turbine is more powerful than the previously built systems.

Die in den Punkten 2,3,4,5 angegebenen Eigenschaften, wurden an einem funktionierenden Modell geprüft. LeerseiteThe properties specified in points 2,3,4,5 were on a working model checked. Blank page
