Description

Zweck der Efindung ist; Schiffen mit kleiner Geschwindigkeit''durch Einbau von Triebtrommeln eine größere Geschwindigkeit zu geben.The purpose of the invention is; Ships through at low speed Installation of drive drums to give a greater speed.

Ein Schiff wird durch seinen Antrieb durch das Wasser gedrückt. Die Er!hiiutg@bestelit darin daß der Druck auf den Bug des Schiffes durch die Drehung von Trommeln vermindert wird; gleichzeitig wird dadurch die Strömung am Schiff günstig heeinfiußt.A ship is pushed through the water by its propulsion. the He! Hiiutg @ bestelit that the pressure on the bow of the ship by the rotation is diminished by drums; at the same time, the current on the ship is favorable heinfiusses.

Abb. a und b stellen ein Schiff mit senkrecht stehenden, parallel zur Bordwand angeordneten Zylindern dar; Abb. c und d stellen ein Schiff mit horizontaler Lage der Zylinder dar. Zur Erhöhung der Wirkung kann eine Aufrauhung der glatten Trommeloberfläche erfolgen, oder es können 'Schaufefradtröin= mein verwendet werden.Fig. A and b represent a ship with vertical, parallel cylinders arranged to the side wall; Fig. C and d represent a ship with horizontal Position the cylinder. To increase the effect, a roughening of the smooth Drum surface, or 'Schaufefradtröin = my' can be used.
