Schraube für Wasser- und Luftfahrzeuge mit in Gruppen versetzt hintereinanderScrew for watercraft and aircraft with staggered in groups one behind the other

angeordneten Flügeln.arranged wings.

Patentiert im Deutschen Reiche vom 13. April 1910 ab. Patented in the German Empire on April 13, 1910.

Die Erfindung betrifft eine Schraube für Wasser- und Luftfahrzeuge mit in Gruppen versetzt hintereinander angeordneten Flügeln. Das Neue besteht darin, daß die Steigung der Flügel vom vorderen zum hinteren Flügel fortschreitend abnimmt.The invention relates to a screw for watercraft and aircraft with in groups wings arranged offset one behind the other. The new thing is that the slope the wing gradually decreases from the front to the rear wing.

Der Erfinder verspricht sich von dieser Ausführung den bekannten Schrauben gegenüber, bei denen die Steigung der vorderen ίο Flügel geringer als die der hinteren ist, eine verbesserte Wirkung.The inventor hopes that this design will result in the known screws, where the pitch of the front ίο wings is less than that of the rear, one improved effect.

Die Fig. ι der Zeichnung zeigt die Schraube in Ansicht von hinten. Fig. 2 ist ein Schnitt nach A-B der Fig. 1. ■The Fig. Ι of the drawing shows the screw in a view from behind. Fig. 2 is a section along AB of Fig. 1. ■

In beiden Figuren zeigt der Pfeil 5 die Drehrichtung an und der Pfeil C- D die Fahrtrichtung des Fahrzeuges.In both figures, the arrow 5 indicates the direction of rotation and the arrow C- D the direction of travel of the vehicle.

Nach der vorliegenden Ausführungsform sind drei Flügel i, 2, 3 angenommen, doch können auch mehr oder weniger Flügel angeordnet sein.According to the present embodiment, three wings i, 2, 3 are assumed, but can more or less wings can also be arranged.

Wie aus Fig. 2 ersichtlich, nimmt die Steigung der einzelnen Flügel vom vorderen nach dem hinteren Flügel zu fortschreitend ab.As can be seen from Fig. 2, the slope of the individual wings decreases from the front the rear wing to advancing off.
