船舵
摘要：
在一种船舵中，其包括一舵叶，舵叶具有一头缘板和一尾缘板，其中舵叶具有两个上下相叠的舵叶部分，其头缘板部分和/或尾缘板部分相互位错，使得其中一个头缘板部分和/或一尾缘板部分向左舷或右舷位错，而另一头缘板部分和/或另一尾缘板部分向右舷或左舷位错，并且所述其中一个头缘板部分和/或一尾缘板部分具有一左舷侧的偏移表面，其凸出于另一头缘板部分和/或另一尾缘板部分，并且所述另一头缘板部分和/或尾缘板部分具有一右舷侧的偏移表面，其凸出于一头缘板部分和/或一尾缘板部分，为了特别在较大的具有高负荷的螺旋桨的船的使用中避免因气穴形成在舵上引起的侵蚀现象和降低或保持低的燃料消耗，在每一偏移表面的区域内设置一覆盖各偏移表面的流动体，该流动体的外部尺寸与各偏移表面的外部尺寸适配地构成。
摘要（英）：

A rudder includes a rudder blade having leading edge sections and trailing edge sections. The rudder blade has two superimposed rudder blade sections, the leading edge sections and/or the trailing edge sections of which are offset such that the one leading edge section and/or the one trailing edge section is offset port or starboard and the other leading edge section and/or the other trailing edge section is offset starboard or port and that the one leading edge and/or trailing edge section has a port-sided offset surface which projects over the other leading edge section and/or the other trailing edge section and the other leading edge section and/or trailing edge section has a starboard-sided offset surface which projects over the one leading edge section and/or trailing edge section, a flow body configured in such a manner that its dimensions are adapted to the dimensions of the offset surfaces, which covers the offset surfaces and which is configured in the area of each offset surface.
