Abstract
Description
Die Erfindung betrifft einen Schiffsantrieb mit auf fest im Schiffskörper oder unter dem Schiffsheck liegenden Antriebswellen angeordneten Propellern.The invention relates to a ship propulsion with on in the hull or under propellers arranged at the stern of the ship.
In der Binnenschiffahrt hat sich bei Schub- und Schleppfahrzeugen (Wassertrecker)
der Voith-Schneider-Propeller als Schiffsantrieb wegen der damit erreichbaren
hohen Manövrierfähigkeit der Einheiten bewährt. Da der Propellerstrahl durch die
relativ einfache konzentrische Verschiebung des Steuerpunktes beliebig gerichtet
werden kann, ist somit der Einbau eines Ruders bei Schiffseinheiten mit einem
Voith-Schneider-Antrieb völlig überflüssig und deshalb ein solches nicht mehr
vorhanden.
Weiterhin haben sich mit der Möglichkeit der Herstellung zuverlässiger Z-Getriebe
auch Antriebsanlagen durchgesetzt, bei der die Schiffsschraube an einem um 360°
drehbaren, stromlinienförmig ausgebildeten Pylon unter dem Schiff befestigt ist.
Diese Ruderpropeller dienen in einer Baueinheit sowohl dem Schiffsantrieb als auch
der Schiffssteuerung.
Den neuesten Stand auf diesem Gebiet stellen die Azipodpropeller dar, wo statt
eines mechanischen Antriebs des Propellers über ein Z-Getriebe der Antrieb über
einen vor dem Propeller gelagerten und mit ihm drehbaren E-Motor erfolgt.
Bei diesem Schiffsantrieb mit innerhalb eines drehbaren Pylons angeordnetem
Propeller entfällt natürlich auch das traditionelle Ruder.
Bei fest auf im Schiffskörper oder unter dem Schiffsheck liegenden Antriebswellen
angeordneten Propellern ist eine Umlenkung des Propellerstrahles jedoch nur dann
möglich, wenn der Propeller innerhalb einer um eine senkrechte Achse verschwenkbaren
Düse rotiert. Diese sogenannten Düsenruder bringen zwar gegenüber
herkömmlichen Rudern eine bessere Ruderwirkung, jedoch kann nicht auf die
Anordnung zweier mechanisch getrennter Einheiten - Schubantrieb und
Schiffssteuerung - verzichtet werden. In inland navigation, the Voith-Schneider propeller has proven itself as a ship propulsion system for push and towing vehicles (water tractors) because of the high maneuverability of the units. Since the propeller jet can be directed as desired due to the relatively simple concentric shift of the control point, the installation of a rudder in ship units with a Voith-Schneider drive is completely unnecessary and therefore no longer available.
Furthermore, with the possibility of producing reliable Z-gears, propulsion systems have also become established, in which the propeller is attached to a pylon which can be rotated through 360 ° and is formed in a streamlined manner under the ship. These rudder propellers are used in one structural unit for both ship propulsion and ship control.
The latest state of the art in this area are the Azipod propellers, where instead of a mechanical drive of the propeller via a Z gear, the drive takes place via an electric motor mounted in front of the propeller and rotatable with it. Of course, the traditional rudder is also omitted in this ship propulsion system with a propeller arranged within a rotatable pylon.
In the case of propellers which are arranged fixedly in the hull or under the stern of the ship, however, deflection of the propeller jet is only possible if the propeller rotates within a nozzle which can be pivoted about a vertical axis. Although these so-called jet rudders have a better rudder effect than conventional rudders, it is not possible to dispense with the arrangement of two mechanically separate units - thrust drive and ship control.
Aufgabe der Erfindung ist es, einen Schiffsantrieb mit fest auf im Schiffskörper oder unter dem Schiffsheck liegenden Antriebswellen angeordneten Propellern zu schaffen, insbesondere für Schub- und Binnenschiffe, mit dem sowohl eine optimale Schubkraft für die Vorwärts- und Rückwärtsfahrt erreicht werden kann als auch die Steuerbewegungen des Schiffsobjektes ausgeführt werden können.The object of the invention is to provide a ship propulsion with or in the hull propellers located under the stern of the ship are arranged create, especially for pushers and barges, with which both an optimal Thrust for forward and reverse travel can be achieved as well Control movements of the ship object can be carried out.
Erfindungsgemäß wird die Aufgabe dadurch erreicht, daß die fest im Schiffskörper
oder unter dem Schiffsheck liegenden Antriebswellen paarweise im Bereich von
knapp oberhalb bis knapp unterhalb der Wasseroberfläche, der Konstruktionswasserlinie,
angeordnet werden und daß am Heck des Wasserfahrzeugs auf den
Schwanzenden der paarweisen Propellerwellen an der Oberfläche drehende
Verstellpropeller montiert werden, so daß der Drehkreis der sogenannten
Oberflächen-Verstell-Propeller sich zumindest 30% oberhalb der Wasseroberfläche
befindet, und daß das Wasserfahrzeug ohne ein zusätzliches Steuerorgan, z.B. ein
Ruder, ausgerüstet wird.
Erfindungsgemäß werden vorzugsweise am Heck des Wasserfahrzeugs zwei im
wesentlichen nebeneinander liegende und bei normaler Marschfahrt entgegengesetzt
drehende Oberflächen-Verstell-Propeller vorgesehen.
Die Ausführung von Steuermanövern wird erfindungsgemäß sowohl durch die
Verstellung der Propellerflügel als auch durch das Umsteuern der Drehrichtung eines
der beiden Propeller erreicht, so daß dann der Schaufelradeffekt beider Oberflächen-Verstell-Propeller
in gleicher Richtung zur Wirkung gebracht wird.
Erfindungsgemäß werden weiterhin die Propellerwellen jeweils in einem
Winkelbereich von 0° bis 45°, vorzugsweise von 0° bis 20°, zur Schiffslängsachse in
der horizontalen Ebene angeordnet, um durch Überlagerung der Schubkraft- und der
Querkraftkomponenten einen größeren Kraftvektor in Bewegungsrichtung des
Schiffes zu erreichen.
Da die relativ großen Propellerdurchmesser, die hohen Flügelzahlen und die großen
Nabendurchmesser bei Propellern aus Bronze zu hohen Propellergewichten führen,
sollten zur Vermeidung dieser hohen Propellergewichte die Flügel der Oberflächen-Verstell-Propeller
erfindungsgemäß aus Faserverbundwerkstoffen gefertigt werden.According to the invention the object is achieved in that the drive shafts fixed in the hull or under the ship's stern are arranged in pairs in the range from just above to just below the water surface, the construction waterline, and in that at the stern of the watercraft on the tail ends of the paired propeller shafts on the surface rotating propellers are mounted so that the turning circle of the so-called surface propellers is at least 30% above the water surface, and that the watercraft is equipped without an additional control element, such as a rudder.
According to the invention, two surface-adjusting propellers which are essentially adjacent to one another and rotate in the opposite direction during normal cruising are preferably provided at the stern of the watercraft.
The execution of control maneuvers is achieved according to the invention both by adjusting the propeller blades and by reversing the direction of rotation of one of the two propellers, so that the impeller effect of both surface-adjusting propellers is then brought into effect in the same direction.
According to the invention, the propeller shafts are each arranged in an angular range of 0 ° to 45 °, preferably 0 ° to 20 °, to the longitudinal axis of the ship in the horizontal plane in order to achieve a larger force vector in the direction of movement of the ship by superimposing the thrust and transverse force components .
Since the relatively large propeller diameters, the large number of blades and the large hub diameters lead to high propeller weights in bronze propellers, the blades of the surface-adjusting propellers should be manufactured according to the invention from fiber composite materials in order to avoid these high propeller weights.

Bei einer Anordnung der Oberflächenpropellern hinter dem Schiff ist die Verwendung
von zusätzlichen Rudern nicht nötig, da eine Steuerung des Schiffes nur mit dem
Propeller möglich ist. Die Besonderheit des oberflächendurchstoßenden Propellers
ist, daß die Flügel nur mit der unteren Propellerkreisfläche ins Waser eintauchen und
somit stets eine Querkraft am Propeller vorhanden ist. Diese Querkräfte des
Propellers können zum Steuern ausgenutzt werden.
Durch die paarweise Kombination von zwei Oberflächen-Verstell-Propellern ist die
Möglichkeit einer universellen Steuerung durch die in zwei Richtungen steuerbare
Kraftvektoren Schub und Querkraft je Propeller gegeben.Erreicht wird dies durch die
Kombination von Drehzahl/Richtung mit einer Steigungsverstellung. Entsprechend
Fig. 2 lassen sich theoretisch damit alle Bewegungsformen auch ohne Ruder bzw.
Bugstrahlruder in der horizontalen Ebene erreichen. Voraussetzung ist eine
universelle Steuermöglichkeit von Steigung, Drehzahl und Drehrichtung jedes
Propellers. Am günstigsten wird das durch ein dieselelektrisches Steuerkonzept
verwirklicht.
In den ersten beiden Spalten der Fig. 2 ist die achsparallele Anordnung der
Propellerachsen dargestellt, in der dritten Spalte eine schuboptimierte, leicht aus der
Schiffslängsachse herausgedrehte Variante.
Im Weiteren soll das Bewegungskonzept anhand der schuboptimierten Variante
vorgestellt weden. Beim Antrieb eines Propellers bildet sich eine Schubkomponente
und eine Querkraft. Diese beiden Komponenten können durch Variation von
Steigung und Drehzahl zueinander verändert werden. Prinzipiell ist damit die
Möglichkeit gegeben, mit einem Propeller geradeaus zu fahren und auch leichte
Drehungen/Versetzungen durchzuführen. Durch die Verwendung von zwei
Propellern ergeben sich jedoch erheblich günstigere Steuereigenschaften.If the surface propellers are arranged behind the ship, the use of additional oars is not necessary, since control of the ship is only possible with the propeller. The peculiarity of the surface piercing propeller is that the wings only dip into the water with the lower propeller circle and thus there is always a lateral force on the propeller. These transverse forces of the propeller can be used for steering.
The combination of two surface-adjustable propellers in pairs enables universal control by means of the thrust and lateral force force vectors, which can be controlled in two directions, by combining the speed / direction with a pitch adjustment. According to FIG. 2, all forms of movement can theoretically be achieved even without an oar or bow thruster in the horizontal plane. The prerequisite is a universal control option for the pitch, speed and direction of rotation of each propeller. The cheapest way to do this is with a diesel-electric control concept.
The first two columns of FIG. 2 show the axially parallel arrangement of the propeller axles, in the third column a thrust-optimized variant which is slightly twisted out of the longitudinal axis of the ship.
Furthermore, the movement concept will be presented using the thrust-optimized variant. When driving a propeller, a thrust component and a lateral force are formed. These two components can be changed by varying the incline and speed. In principle, this gives you the option of driving straight ahead with a propeller and also making slight turns / displacements. However, the use of two propellers results in considerably more favorable control properties.
Die einzelnen Bewegungsformen werden dabei wie folgt erzielt:The individual forms of movement are achieved as follows:
Die Propeller drehen entgegengesetzt. Die Steigung entspricht einem für die Leistungsumsetzung optimalen Punkt. Die Querkräfte heben sich durch die entgegengesetzte Drehrichtung auf.The propellers turn in the opposite direction. The slope corresponds to one for the Performance implementation optimal point. The lateral forces rise through the opposite direction of rotation.
Die Drehzahl der Propeller oder Leistungsumsetzung ist an jedem Propeller unterschiedlich. Bei voller Leistungsumsetzung hat der Propeller mit der geringeren Drehzahl eine höhere Steigung. Dadurch wird die Querkraft wesentlich vergrößert. Es erfolgt eine Drehung, kombiniert mit einem Versatz.The speed of the propeller or power conversion is on each propeller differently. With full power conversion, the propeller with the lower one Speed a higher slope. This significantly increases the lateral force. There is a rotation combined with an offset.
Es arbeitet nur ein Propeller oder beide Propeller haben die gleiche Drehrichtung bei gleicher Steigungsrichtung. Only one propeller is working or both propellers are rotating in the same direction same slope direction.
Ein Propeller arbeitet mit Schubvektor voraus und einer Querkraftrichtung. Der andere Propeller arbeitet mit rückwärtsgerichtetem Schubvektor und mit einem in die gleiche Richtung wie der erste Propeller weisenden Querkraftvektor.A propeller works with a thrust vector ahead and a direction of transverse force. The other propeller works with rearward thrust vector and with one in same direction as the first propeller pointing shear force vector.
Beide Propeller arbeiten mit entgegengesetzter Drehrichtung gleicher Steigungseinstellung und rückwärtsgerichtetem Schubvektor.Both propellers work with the same direction of rotation Incline adjustment and rearward thrust vector.
