[과제] 선체의 선미에 설치한 선미정류구조에 의해 프로펠러면에 유입하는 흐름을 정류하는 것에 의해, 프로펠러의 효율을 보다 높이는 것과 함께, 정류할 때에 선미정류구조에 작용하는 추력성분을 보다 크게 해서 추진성능을 보다 향상하는 것이 가능한 것과 함께, 구조적으로도 견고한 선미정류구조 및 선박을 제공한다. [해결수단] L자형 선미정류판(5A)과 추력발생보조부재(5B)로 이루어지고, L자형 선미정류판(5A)을, 선박(1)의 선체(2)의 선미의 외판상에 선체폭방향으로 돌출해서 설치되고, 선체폭방향으로 연장된 기판부분(10)과, 이 기판부분(10)의 선체폭방향의 단부에 설치된 위쪽으로 꺾여진 절곡부분(13)을 갖고서 구성하는 것과 함께, 추력발생보조부재(5B)를 L자형 선미정류판(5A)의 하부와 선체(2) 사이에, 경사각도(α1)를 수평에 대해서 외측이 위쪽으로 향하는 각도로 0도보다도 크고 또한, 45도 이하로 해서 설치하여 구성한다.

    The invention provides a stern rectification structure and a ship which improves efficiency of a propeller by rectifying a flow which is caused to flow into a propeller surface by the stern rectification structure provided on a stern of a hull, can improve propelling performance by enlarging a thrust component working on the stern rectification structure upon rectification and is also rigid structurally. The stern rectification structure comprises an L-letter type stern rectification plate and a thrust generation auxiliary member. Therein, the L-letter type stern rectification plate is configured to have a substrate part which protrudes in a hull width direction on a shell plate of the stern of the hull of a ship and extends in a hull width direction and a bent part which is provided on an end part of the hull width direction of the substrate part and is bent upward. The thrust generating auxiliary member is provided between a lower part of the L-letter type stern rectification plate and the hull while setting an inclination angle as such an angle that the outside proceeds upward with respect to horizontality is larger than 0 degree and 45 degrees or less.
