Rudder for ships with high speeds with a cavitation reducing, twisted, in particular floating rudder

摘要

The rudder comprises a rudder blade (100) and a propeller, where the rudder blade has two rudder blade sections (10,20). An upper front leading edge (11) is off-set towards port-side or starboard. A lower front leading edge (21) is off-set towards starboard or port-side. The lower front leading edge has an offset surface on the starboard side, which protrudes over the upper front leading edge. A flow element (41) is provided in an area of each offset surface formed to fit the size of the offset surface, where the flow element covers the offset surface.
