   Infolge der Leichtigkeit und Elastizität, die man auf solche Weise dem Propeller geben kann, lässt sich die geometrische Erzeugung der Schraube   vereinfachen   und die Steigung vergrössern und infolgedessen die Tourenzahl verringern, was bei gleicher Geschwindigkeit eine Antriebsmaschine von niedrigerer Leistung, als im Falle einer Schraube mit starren Flügeln, anzuwenden und die Kosten für Brennstoff   herabzusetz cu gestattet.   



   Die schädlichen Vibrationen des Schiffskörpers, welche bei Anwendung von Schrauben mit starren Flügeln entstehen und die Gefahr des Bruchs der Schraubenflügel sind ebenfalls in gewissem Grade verringert. 



   Auf die gleiche Art und zu demselben Zwecke kann man auch die Schaufeln der Schaufelräder elastisch ausführen.

   As a result of the lightness and elasticity that can be given to the propeller in this way, the geometrical generation of the propeller can be simplified and the pitch increased and consequently the number of revolutions reduced, which at the same speed results in a drive machine of lower power than in the case of a propeller with rigid wings, apply and reduce the cost of fuel cu allowed.



   The harmful vibrations of the hull, which arise when using propellers with rigid blades, and the risk of the propeller blades breaking are also reduced to a certain extent.



   The blades of the paddle wheels can also be made elastic in the same way and for the same purpose.
