Problems solved by technology

[0014] As mentioned above, for the rudders of Patent Documents 3 and 4, although the above-mentioned part of the problem of cavitation has been solved by the shape of the lower part of the rudder, only the side flow of the lower end of the rudder is considered. The flow under the lower end of the rudder has not been studied, so there is no effective solution to the problem of reducing cavitation

Abstract

The rudder for a ship according to an embodiment of the present invention is characterized in that it includes a rudder body for steering the ship through the wake of the propeller, and when the lower end of the rudder body is viewed from the side, it has a downward direction. Convex curve shape.

Description

technical field [0001] The present invention relates to a rudder for ships. [0002] The present invention was derived from the research conducted as part of the industrial integration source technology development project by the Ministry of Knowledge Economy and the Korea Industrial Technology Evaluation Manager (Project specific number: 10040060; Project title: Improvement of resistance propulsion performance, different ships type of energy-saving add-ons and their application in real ships). Background technique [0003] Generally, a large ship moves forward by using a fluid flow generated when a propeller attached to the stern of the hull rotates. At this time, a rudder is attached to the rear of the propeller, and by turning the rudder left and right, the flow direction of the fluid is adjusted, and the navigation direction is changed. [0004] As described above, in order to achieve a certain speed by the rotation of the propeller, it is necessary to use fuel such as...
