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 embodiment of the invention relates to a rudder for a ship, and the rudder is characterized in that: the rudder comprises a rudder main body which controls the ship through wake flow of a propeller, when the lower side end of the rudder main body is observed from side, the rudder main body is in curve shape with downward projection.

Description

Technical field [0001] The present invention relates to a rudder for ships. [0002] The present invention is derived from research conducted as part of the industrial integration source technology development project, which is the Ministry of Knowledge Economy and the Korean Industrial Technology Evaluation Manager (Project inherent number: 10040060; project name: improvement of resistance propulsion performance, different ships The development of different types of energy-saving additional devices and their applications in actual ships). Background technique [0003] Generally, a large ship uses a fluid flow generated when a propeller installed at the stern of the ship rotates to move forward. At this time, a rudder is attached to the rear of the propeller, and the flow of the fluid is adjusted by turning the rudder to the left and right, thereby changing the navigation direction. [0004] As described above, in order to achieve a certain speed through the rotation of the propell...
