The present invention relates to a pre-swirl stator for a ship and, more specifically, to a pre-swirl stator configured to increase the propulsive efficiency by reducing cavitation generated from the pre-swirl stator and to increase the durability of a propeller. To achieve this end, the pre-swirl stator according to the present invention is located at the front side of the propeller, and has one end fixated to the stern of the ship. In addition, holes penetrating through both sides of the pre-swirl stator are formed at intervals on the other end of the pre-swirl stator.

    본 발명은 선박의 전류고정날개에 관한 것으로서, 특히 전류고정날개에서 발생하는 캐비테이션을 감소시켜 추진효율을 증대시키며 프로펠러의 내구성을 증대시킬 수 있게 구성한 전류고정날개에 관한 것이다. 상기와 같은 목적을 달성하기 위한 본 발명은 프로펠러의 전방에 위치하며 일단이 선미부에 고정되는 전류고정날개들로서, 전류고정날개의 타단에는 전류고정날개의 양측면을 관통하는 홀들이 간격을 두고 형성된 것을 기술적 특징으로 한다.
