    • PROBLEM TO BE SOLVED: To provide a rudder for ships avoiding a corrosion phenomenon of the rudder due to cavitation generation for use in a high speed ship equipped with a high load propeller, and reducing or lowly maintaining fuel consumption.
      SOLUTION: A rudder blade 100 has two superimposed rudder blade sections 10, leading edge sections 11, 21 and/or 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 41 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.

    • 要解决的问题:为船舶提供舵,以避免由于在配备高负载螺旋桨的高速船舶中使用的空化产生的舵的腐蚀现象,并且减少或低维持燃料消耗。 解决方案:方向舵叶片100具有两个叠置的舵叶部分10,前缘部分11,21和/或后缘部分被偏移,使得一个前缘部分和/或一个后缘部分偏移 右舷和另一个前缘部分和/或另一个后缘部分是右舷或右舷偏移,并且一个前缘和/或后缘部分具有突出在另一前缘部分上的端口侧偏移表面, /或另一个后缘部分和另一个前缘部分和/或后缘部分具有突出在一个前缘部分和/或后缘部分上的右舷侧偏移表面。 流体41被构造成使得其尺寸适应于偏移表面的尺寸,该偏移表面覆盖偏移表面并且被配置在每个偏移表面的区域中。 版权所有(C)2009,JPO&INPIT
