The present invention relates to a rudder for a ship, comprising a rudder bulb and, more specifically, to a rudder for a ship, comprising a rudder bulb, the rudder comprising a rudder bulb that protrudes in the direction of a propeller, and capable of increasing the propulsion efficiency of a ship as the front upper part and the front lower part of the rudder are formed to cross each other with the rudder bulb at the center. The rudder for a ship, comprising a rudder bulb of the present invention can decrease the occurrence of cavitation due to a propeller hub by having the rudder bulb, and has the benefit of saving the fuel and propelling efficiency of the ship by enabling easy movement of fluid by having the upper part and the lower part of a front part tilted in crossing directions to correspond to a rotational incident flow.

    La présente invention concerne un gouvernail pour un navire, comprenant un bulbe de gouvernail et, plus spécifiquement, un gouvernail pour un navire, comprenant un bulbe de gouvernail, le gouvernail comprenant un bulbe de gouvernail qui fait saillie dans la direction d'une hélice, et capable d'augmenter l'efficacité de propulsion d'un navire à mesure que la partie supérieure avant et la partie inférieure avant du gouvernail sont formées pour se croiser avec le bulbe de gouvernail au centre. Le gouvernail pour un navire, comprenant un bulbe de gouvernail selon la présente invention peut réduire l'apparition d'une cavitation due à un moyeu d'hélice en ayant le bulbe de gouvernail, et a l'avantage d'économiser le carburant et l'efficacité de propulsion du navire en permettant un mouvement facile du fluide en ayant la partie supérieure et la partie inférieure d'une partie avant inclinée dans des directions de croisement pour correspondre à un flux incident de rotation.

    본 발명은 러더벌브를 포함하는 선박용 방향타에 관한 것으로서, 더욱 상세하게는 프로펠러 방향으로 돌출된 러더벌브를 포함하며 러더벌브를 기준으로 전단 상부와 전단 하부가 엇갈리게 형성되어 선박의 추진효율을 높일 수 있는 러더벌브를 포함하는 선박용 방향타에 관한 것이다. 본 발명의 러더벌브를 포함하는 선박용 방향타는 러더벌브가 형성되어 있어 프로펠러 허브에 의한 캐비테이션 발생을 줄일 수 있으면서, 회전입사류의 흐름에 대응되게 전단부 상부와 하부가 엇갈리는 방향으로 편향되어 있어 유체의 이동이 용이함에 따라 선박의 추진효율 및 연료를 절감할 수 있는 이점이 있다.
