Description

Beim Starten wird bei den üblichen Schrauben das Wasser mit größer Kraft nach der Seite ausgestoßen, nach welcher sich die Schraube dreht, und dadurch werden Wellen verursacht. Durch Ausschaltung dieses nutzlosen Kräfteverbrauches ist eine große Treibstoffeinsparung und vollkommene Geräuschlosigkeit möglich, und das Fahrwasser verbleibt in ruhigem Zustand. Zur Vermeidung des Wellenschlages und zur Erhöhung des Wirkungsgrades werden bei einer zweiflügeligen Schraube erfindungsgemäß die Flügel an je einem Arm angebracht und haben eine in Fahrtrichtung geneigte Erzeugende. Der Schiffsrumpf erhält dann keinerlei Erschütterungen. In der Zeichnung ist die Schraube in drei Ansichten dargestellt. Die Steigung der Flügelflächen ist in den Schnitten A-B; C-D, E-F, G-H ersichtlich. Bei Drehung der Schraube werden durch die Form und die Lage der Flügel die verarbeiteten Wassermengen in das Kielwasser gepreßt, wo sie sich spurlos verteilen.When starting, the water increases with the usual screws Force ejected to the side that the screw turns, and thereby waves are caused. By eliminating this useless use of energy great fuel savings and complete silence are possible, and the fairway remains calm. To avoid the waves and to increase the efficiency are according to the invention with a two-wing screw the wings are attached to one arm each and have a generating line inclined in the direction of travel. The hull then does not receive any vibrations. In the drawing is the Screw shown in three views. The slope of the wing surfaces is in the Sections A-B; C-D, E-F, G-H can be seen. When the screw is turned, through the shape and location of the wings the amount of water processed in the wake pressed where they spread without a trace.
