Ebenso bekannt sind Schiffsruder mit einem twistierten Ruderblatt, das aus zwei übereinanderliegenden Ruderblattabschnitten besteht, deren dem Propeller zugekehrte Nasenleisten derart seitlich versetzt sind, dass die eine Nasenleiste nach Backbord und die andere Nasenleiste nach Steuerbord versetzt ist.Ship rudders, such as full-floating rudder or balance rudder, with or without hinged fin, are known in various embodiments.

Da das bekannte Ruderblatt sich nicht nach unten konisch verjüngt, sondern von oben bis unten einen gleichbleibenden Querschnitt bzw. eine gleichbleibende Querschnittsgröße aufweist, sind alle Querschnittsflächen gleich groß, unabhängig davon, dass der obere Ruderblattabschnitt nach einer Seite ausschwenkt und der untere Ruderblattabschnitt zur anderen Seite ausschwenkt.Since the known rudder blade does not taper conically downwards, but has a constant cross-section or a constant cross-sectional size from top to bottom, all cross-sectional areas are equal, regardless of the fact that the upper rudder blade section pivots out to one side and the lower rudder blade section to the other side swings.
Nach einer weiteren Ausführungsform besteht das Ruderblatt aus zwei Blattabschnitten, die übereinanderliegend angeordnet sind. Beide Blattabschnitte weisen gleiche Querschnitte auf, deren größte seitliche Ausbiegung in Höhe der Propellerachse liegt. Die dem Propeller abgekehrten Endleisten fallen nicht zusammen. Dadurch, dass diese Endleisten weit auseinanderstehen, werden völlig andere Querschnittsverhältnisse geschaffen. Außerdem fallen die dem Propeller zugekehrten Nasenleisten der beiden Ruderblattabschnitte ineinander zu einer geradlinig verlaufenden Nasenleisten. Dagegen weist jeder Ruderblattabschnitt eine Endleiste auf.According to a further embodiment, the rudder blade consists of two blade sections, which are arranged one above the other. Both blade sections have the same cross sections, the largest lateral deflection is equal to the propeller axis. The propellers facing away Endleisten do not coincide. The fact that these end strips are far apart, completely different cross-sectional conditions are created. In addition, the propeller facing nose strips of the two rudder blade sections coincide with each other to a straight-running nose strips. In contrast, each rudder blade section has an end bar.
