Description

Schraubenpropeller. -Es sind Schraubenpropeller bekannt, bei denen die eine Kante der Flügel nach einer geraden Linie verläuft, die in ihrer Verlängerung entweder durch die Drehachse hindurch-oder in bezug auf die Flügelfläche vor der Drehachse vorbeigeht. Diese Schrauben sind so konstruiert, daß die geraden Kanten der Flügel beim Betriebe die Eintrittskanten sind.Screw propeller. - Screw propellers are known where one edge of the wing runs in a straight line that is in its extension either through the axis of rotation or in relation to the wing surface in front of the Axis of rotation passes. These screws are designed so that the straight edges the wing in operation are the leading edges.

Gegenstand der Erfindung ist nun eine Schraube, bei der, ebenso wie bei den bekannten Schrauben, die eine Flügelkante nach einer Geraden verläuft. Abweichend von den bekannten Schrauben ist aber die neue Schraube so konstruiert, daß die geraden Flügelkanten die Austrittskanten sind.The invention now relates to a screw in which, as well as with the known screws, which one wing edge runs in a straight line. Different of the known screws, however, the new screw is designed so that the straight Wing edges are the trailing edges.

Ein solcher Propeller ist auf der Zeichnung in zwei Ausführungsformen dargestellt, rund zwar zeigt Abb. = einen Flügel, dessen gerade-Austrittskante durch die Drehachse hindurchgeht, während diese Kante bei Abb. a vor der Drehachse vorbeigeht. Zweck der neuen Anordnung ist die Erzielung eines besseren Wirkungsgrades.Such a propeller is in the drawing in two embodiments shown, although Fig. = shows a wing, the straight trailing edge through the axis of rotation passes through it, while this edge in Fig. a passes in front of the axis of rotation. The purpose of the new arrangement is to achieve better efficiency.
