A rudder having a variable steering force is disclosed. The disclosed invention comprises: a rotary coupling unit installed in a hull; a first rudder blade installed in the rotary coupling unit; and a second rudder blade installed in the rotary coupling unit to control a distance from the first rudder blade. According to the present invention, the rudder can reduce a radius of the hull by increasing a steering force when the hull is rotated and control a thickness depending on a situation to simultaneously improve steering performance and traveling performance.
타력 가변형 러더에 대한 발명이 개시된다. 개시된 발명은: 선체에 설치되는 회전결합부와; 회전결합부에 설치되는 제1러더블레이드; 및 제1러더블레이드와의 간격이 조절되도록 회전결합부에 설치되는 제2러더블레이드를 포함한다. 본 발명에 의하면, 선체 선회시 타력을 증가시켜 선체 반경을 감소시킬 수 있을 뿐 아니라, 상황에 따라 두께를 조절하여 조향성능과 주행성능을 함께 향상시킬 수 있다.
