Description

Bekannt sind Steuerruder für Einschraubenschiffe, durch die neben der auf den Schiffskörper ausgeübten Steuerwirkung gleichzeitig eine Düsenwirkung im Propellerström hervorgerufen wird. Zur Erzielung dieser Wirkungen ist vorgeschlagen worden, das Ruder als Zylinder mit Düsenform auszubilden, der den Propeller umschließt oder hinter dem Propeller angeordnet ist. Die Anwendung solcher Ruder für Mehrschraubenschiffe war bisher nicht möglich, weil der Durchmesser des zylindrischen Ruders zu groß wurde.Are known rudders for single-screw ships, through the addition to the Hull exerted control effect at the same time a nozzle effect in the propeller flow is caused. To achieve these effects, it has been proposed that Train rudder as a cylinder with a nozzle shape that surrounds the propeller or behind the propeller is arranged. The application of such rudders for multi-screw ships was previously not possible because the diameter of the cylindrical rudder was too large became.

Die Erfindung richtet sich auf ein Ruder mit Düsenwirkung für Zweischraubenschiffe, die große Breite und geringen Tiefgang haben.The invention is directed to a rudder with a nozzle effect for two-screw ships, which have great breadth and shallow draft.

Gemäß der Erfindung besteht das Ruder aus zwei hinter den Propellern angeordneten Ruderkörpern mit Profilform, die durch zwei stromlinienförmige Traversen miteinanderAccording to the invention, the rudder consists of two arranged behind the propellers Rudder bodies with profile shape, which are connected to each other by two streamlined cross members

Die stromlinienförmigen Ruderkörper O1 und O2 sind hinter den Propellern im Bereich der Propellerströme angeordnet. Die Ruderkörper sind durch die horizontalen Traver-The streamlined rudder bodies O 1 and O 2 are arranged behind the propellers in the area of the propeller flows. The rudder bodies are through the horizontal traverses

, sen h± und &2> die ebenfalls Stromlinienform haben und am Umfang der beiden Schraubenströme tangential zu diesen angeordnet, wer- den, miteinander zu einem geschlossenen, düsenartig wirkenden Rahmen verbunden. Es werden, dadurch eindeutige Strömungsverhältnisse an den Ruderkörpern und damit maximale Querkräfte und ferner eine Verbesserung der Propellerschubwirkung durch Vergrößerung der Propellerstrahlfläche erreicht. , H ± sen and &2> di e have also streamlined shape and disposed tangential to these at the circumference of the two coil currents, the advertising connected to each other to form a closed, acting like a nozzle frame. As a result, clear flow conditions on the rudder bodies and thus maximum transverse forces and, furthermore, an improvement in the propeller thrust effect by increasing the propeller jet area are achieved.

Der Antrieb der Ruderkörper at und a2 erfolgt durch den Ruderschaft ά. Zur Erhöhung der Festigkeit des düsenartigen Rahmens +5 wird ein durchgehender Rudersteven c vorgesehen, um den die beiden Ruderkörper O1 und a2 geschwenkt werden. Die hinter dem zylindrischen Steven c auftretenden Wirbel werden durch die Anordnung einer Verkleidung ßa vermieden.The rudder bodies a t and a 2 are driven by the rudder stock ά. To increase the strength of the nozzle-like frame +5, a continuous rudder stem c is provided around which the two rudder bodies O 1 and a 2 are pivoted. The eddies occurring behind the cylindrical stem c are avoided by arranging a cladding ß a.

Die Traversen bt und b2 bewirken außerdem eine Dämpfung der Stampfbewegungen des Fahrzeugs.The traverses b t and b 2 also have the effect of damping the pitching movements of the vehicle.
