The present invention relates to a pre-swirl stator for a ship stern. More specifically, cavitation generated in the pre-swirl stator is reduced to improve propulsion efficiency and to prevent a propeller from being damaged by cavitation generated in an end of the pre-swirl stator. To achieve the purpose, the present invention is the pre-swirl stators, of which one end is fixated to the ship stern, positioned in a front portion of the propeller. A plurality of pins are fixated at constant intervals in a width direction of the pre-swirl stator in the other end of the pre-swirl stator.

    본 발명은 선박의 전류고정날개에 관한 것으로서, 특히 전류고정날개에서 발생하는 캐비테이션을 감소시켜 추진효율을 증대시키며 전류고정날개 끝단에서 발생하는 캐비테이션으로부터 프로펠러의 손상을 방지할 수 있게 구성한 전류고정날개에 관한 것이다. 상기와 같은 목적을 달성하기 위한 본 발명은 프로펠러의 전방에 위치하며 일단이 선미부에 고정되는 전류고정날개들로서, 전류고정날개의 타단에는 복수의 핀들이 전류고정날개의 폭방향으로 간격을 두고 고정된 것을 기술적 특징으로 한다.
