Abstract

To produce a transverse thrust in ships at speeds at which the rudder has not yet reached its full effectiveness, one or more rotors are arranged one behind the other. Due to their rotation and the oncoming flow in the longitudinal direction of the ship, the rotors produce buoyancy transversely to the ship. So that the shape of the ship is not impaired, the rotors are retracted into the hull when not in use.

Description

Die Erfindung betrifft einen Rotor zur Erzeugung von Querschub bei Schiffen.The invention relates to a rotor for generation of transverse thrust in ships.

Die Erzeugung von Querschub soll die Steuerfähigkeit von Schiffen, besonders bei niedrigen Geschwindig­ keiten, bei denen das Schiffsruder noch nicht seine volle Steuerfähigkeit erreicht, verbessern. Die Erzeugung des Querschubes soll sich über einen möglichst großen Geschwindigkeitsbereich erstrecken.The generation of transverse thrust is said to be controllable of ships, especially at low speeds where the rudder is not yet full tax ability reached, improve. The Generation of the transverse thrust should take place over a extend the largest possible speed range.

Es ist bekannt, zur Erfüllung dieser Erfordernisse Querstrahlruder z. B. im Bugbereich anzuordnen. Die Wirkung dieser Querstrahlruder beruht darauf, daß Wasser in eine bestimmte Richtung beschleunigt wird. (DE-AS 22 63 984, DE-AS 23 15 447, DE-OS 24 38 305, DE-OS 28 12 293, DE-OS 32 41 119, DE-OS 36 09 032, P 32 01 654, P 27 33 340).It is known to meet these needs Aileron z. B. to arrange in the bow area. The effect of this thruster is based on that water accelerates in a certain direction becomes. (DE-AS 22 63 984, DE-AS 23 15 447, DE-OS 24 38 305, DE-OS 28 12 293, DE-OS 32 41 119, DE-OS 36 09 032, P 32 01 654, P 27 33 340).

Der Schub eines solchen Querstrahlers läßt bei wachsender Schiffsgeschwindigkeit erheblich nach, so daß die Wirkung bereits nachläßt, bevor die Wirkung des Schiffsruders einsetzt.The thrust of such a transverse radiator is not increasing ship speed significantly, so that the effect wears off before the Effect of the ship's rudder.

Der Erfindung liegt die Aufgabe zugrunde, auch bei höherer Schiffsgeschwindigkeit einen wirksamen Querschub zu liefern.The invention is based, also with the task higher ship speed an effective Deliver cross thrust.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein sich um seine Achse drehender Rotor von Wasser in Schiffslängsrichtung angeströmt wird und dadurch eine Querkraft erzeugt. According to the invention, this object is achieved by that a rotor of Water flows in the longitudinal direction of the ship and thereby creating a shear force.  

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein Querschub bei fahrendem Schiff erzeugt wird, der mit steigender Schiffsgeschwin­ digkeit anwächst.The advantages achieved with the invention exist especially in that a transverse thrust when moving Ship is generated, with increasing ship speed growing.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigtAn embodiment of the invention is in the Drawing shown and is closer below described. It shows

Fig. 1 die Anordnung des Rotor-Querruders als Bugruder im Schiff, Fig. 1 shows the arrangement of the rotor-aileron as bow rudder of the ship,

Fig. 2 ein Querschnitt durch das Rotor-Querruder. Fig. 2 shows a cross section through the rotor ailerons.

Der Rotor (1) ist mit einer oberen (2) und einer unteren (3) mitrotierenden Endscheibe versehen. Die obere Endscheibe schließt bei ausgefahrenem Rotor mit dem Schiffsboden ab, während dies bei ein­ gefahrenem Rotor die untere tut. Die hydraulische Hubmechanik (4) fährt den Rotor aus, wenn Querschub benötigt wird und zieht ihn anderenfalls wieder ein. Der Antriebsmotor (5) versetzt den Rotor in eine Rechts- oder Linksdrehung je nachdem, ob Steuerbord- oder Backbordschub erzeugt werden soll. Über den Rotorschaft (6) und das Lager (7) wird der Schub auf das Schiff übertragen.The rotor ( 1 ) is provided with an upper ( 2 ) and a lower ( 3 ) rotating end plate. The upper end plate is flush with the ship's bottom when the rotor is extended, while the lower end does when the rotor is in motion. The hydraulic lifting mechanism ( 4 ) extends the rotor when cross thrust is required and pulls it back in again. The drive motor ( 5 ) rotates the rotor clockwise or counterclockwise depending on whether starboard or port thrust is to be generated. The thrust is transferred to the ship via the rotor shaft ( 6 ) and the bearing ( 7 ).
