Abstract

The marine propulsion system has a line of propellers (4) mounted at the bows (6) of the ship. These are mounted in a tunne (1, 2) below the water line, so that a suction effect is created in the part (1) in front of the propellers, and compression in the part (2) behind them. A rudder (3) is mounted at the input to the suction zone (2), and also acting as a stabiliser. This operates to steer the bows.

Description

Beschreibung des Schiffstyps "Saugverdränger"Description of the ship type "suction displacement"

i Saugeingang Druckausgang 7 Druckausgangruder 4 Propeller 5 Wasseroberfläche 6 Bug 7 maugeingangruder Der Saugverdränger ist eine Weiterentwicklung des Verdrangers. Beide Typen müssen, um sich vorwärts bewegen zu können, daß vor dem Bug sich stauende Wasser verdrängen. Beim Verdränger liegt der Antrieb unter dem Heck, daher hat er einen passiven Bug. Beim Saugverdränger liegt der Antrieb im Bug, er hat einen aktiven Bug.i suction inlet pressure outlet 7 pressure outlet rudder 4 propeller 5 water surface 6 Bow 7 Maugeingangruder The suction displacement is a further development of the displacement. Both types must, in order to be able to move forward, that jamming in front of the bow To displace water. With the displacer, the drive is under the stern, so it has a passive bug. In the case of the suction displacement, the drive is in the bow, it has an active one Bug.

Der sich vorwärts bewegende Verdränger setzt das verdrängte Wasser nach rechts, links und nach unten in Bewegung; es entsteht Energie, die der Fortbewegung des Schiffes nicht mehr schadet, aber auch nicht nützt. Der Heckpropeller, der Wasser zum An--trieb benötigt, saugt sich die entsprechenden Mengen unter dem Schiff an.The displacer moving forward sets the displaced water to the right, left and down in motion; it creates energy that is needed for locomotion no longer harms the ship, but is also of no use. The stern propeller, the water needed for propulsion, the corresponding quantities are sucked in under the ship.

Der Saugverdränger teilt das Wasser vor dem Bug nicht, sondern saugt es ein. Der zwischen Saugeingang (1) und Druckausgang (2) befindliche Propeller (4) setzt die Wassermengen in Bewegung und stößt sie entgegen der Fahrtrichtung unter dem Bug (6) wieder aus. Das zur Steuerung des Schiffes benötigte Ruder (3) sitzt im Druckausgang. Das Saugeingangruder (7) soll bei stärkerem Wellengang den Eintritt von Luft in den Saugeingang verhindern, damit der antrieb durch die geringere Dichte der Luft nicht gestört wird.The suction displacer does not split the water in front of the bow, but sucks it a. The propeller located between the suction inlet (1) and pressure outlet (2) (4) sets the amount of water in motion and pushes it against the direction of travel under the bow (6) again. The rudder needed to steer the ship (3) sits in the pressure outlet. The suction inlet rudder (7) should be used in heavy swell Prevent air from entering the suction inlet so that the drive through the lower Density of the air is not disturbed.
