Abstract
Description
Die Erfindung betrifft ein Wasserfahrzeug, insbesondere ein Schiff und insbesondere die Ausgestaltung des Rumpfes eines Schiffs. Die Erfindung findet jedoch ebenso auch bei Luftfahrzeugen Anwendung.The invention relates to a watercraft, in particular a ship and in particular the design of the hull of a ship. The invention however, it is also used in aircraft.
Aus ökologischen und ökonomischen Gründen ist es von Vorteil, den Strö mungswiderstand von Wasserfahrzeugen zu reduzieren. Bei größeren Schiffen hat man überraschenderweise herausgefunden, daß ein Bugwulst diesbezüglich vorteilhaft ist. Bei diesem Bugwulst handelt es sich um eine in Verlängerung des Kiels am Bug angeordnete vorspringende Nase.For ecological and economic reasons it is advantageous to to reduce the drag of water vehicles. For larger ships it has surprisingly been found that a bow bulge is advantageous in this regard. This bulge is an in Extension of the keel projecting nose arranged on the bow.
Der Erfindung liegt die Aufgabe zugrunde, ein mit einem Bugwulst ausgestattetes Schiff bzw. Wasserfahrzeug bezüglich seines Strömungswiderstandes weiter zu optimieren.The invention has for its object a with a bow equipped ship or watercraft with regard to its To further optimize flow resistance.
Zur Lösung dieser Aufgabe wird mit der Erfindung ein Schiff mit einem Schiffrumpf, der sich entlang einer Längsachse zwischen seinem Bug und seinem Heck erstreckt, und einem Bugwulst, der in Erstreckung der Längsachse vom Bug absteht, vorgeschlagen. Bei einem derartigen Schiff ist erfindungsgemäß vorgesehen, daß der Bugwulst um eine Achse drehbar ist, die parallel zur Längsachse des Schiffrumpfes verläuft.To solve this problem, the invention is a ship with a Ship hull, which extends along a longitudinal axis between its bow and its stern extends, and a bow bulge that extends into the Longitudinal axis protrudes from the bow, proposed. With such a ship provided according to the invention that the bow bulge is rotatable about an axis, which runs parallel to the longitudinal axis of the hull.
Durch die Drehbarkeit des Bugwulstes läßt sich der Strömungswiderstand des Schiffes weiter reduzieren. Damit ist es möglich, den Bugwulst sowohl drehend anzutreiben als auch lediglich frei drehbar zu lagern. Im letztgenannten Fall wird der Bugwulst von der Wasserströmung bei Fahrt des Schiffes mitgedreht. Auch dies reduziert merklich den Strömungswiderstand. Die drehende Mitnahme des Bugwulstes durch das entlangströmende Wasser wird verbessert, wenn der Bugwulst eine profilierte Oberfläche aufweist. Diese Oberfläche weist insbesondere nach Art eines Gewindes angeordnete schraubenlinienförmige auf der Bugwulstoberfläche verlaufende Nuten und/oder Erhebungen auf.Due to the rotatability of the bow, the flow resistance of the Reduce ship further. This makes it possible to both rotate the bow to drive as well as just to rotate freely. In the latter case the bow of the bow is rotated by the water flow when the ship is moving. This also significantly reduces the flow resistance. The rotating one The bow bulge is carried along by the flowing water improved if the bow has a profiled surface. This Surface has in particular arranged in the manner of a thread helical grooves running on the surface of the bow bulge and / or surveys.
Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.The invention is explained below with reference to the drawing.
In der Zeichnung ist der vordere Teil 10 eines Schiffrumpfes 12 gezeigt, der sich ausgehend vom Bug 14 entlang einer Längsachse 16 bis zum (nicht dargestellten) Heck erstreckt. In Verlängerung des Kiels 18 befindet sich am Bug 14 ein sogenannter Bugwulst 20. Dieser Bugwulst 20 ist um eine Achse 22 frei und/oder drehend antreibbar gelagert. Diese Drehachse 22 verläuft parallel zur Längsachse 16 des Schiffrumpfes 12. Die Oberfläche 24 des Bugwulstes 20 ist profiliert, was durch schraubenlinienförmig verlaufende Erhebungen und Nuten 26, 28 realisiert ist. Aufgrund der profilierten Oberfläche 24 wird der Bugwulst 20 durch die bei Fahrt des Schiffes entlangstreichende Wasserströmung mitgenommen und in Rotation um die Drehachse 22 versetzt. Dies reduziert den Strömungswiderstand des Schiffrumpfes 12.In the drawing, the front part 10 of a ship's hull 12 is shown, which extends from the bow 14 along a longitudinal axis 16 to the stern (not shown). In the extension of the keel 18 , a so-called bow bead 20 is located on the bow 14 . This bulge 20 is freely and / or rotatably supported about an axis 22 . This axis of rotation 22 runs parallel to the longitudinal axis 16 of the hull 12 . The surface 24 of the bow bulge 20 is profiled, which is realized by helical elevations and grooves 26 , 28 . Because of the profiled surface 24 , the bow bulge 20 is carried along by the water flow sweeping along when the ship is traveling and set in rotation about the axis of rotation 22 . This reduces the flow resistance of the hull 12 .
