The present invention relates to a pre-swirl stator including an annular structure, to improve structural stability. According to the present invention, the pre-swirl stator including an annular structure is installed in the front side of a propeller at a stern part of a vehicle, and comprises: a plurality of pre-swirl stators radially installed around a rotational central axis of a propeller; and the annular structure installed to surround end parts of the pre-swirl stators. The pre-swirl stators are left-right symmetrically installed with a vertical shaft passing through the rotational central axis of the propeller, the annular structure has a diameter with respect to 40 to 60% of the diameter of the propeller, and the chord length of the annular structure is greater than that of the end part of the pre-swirl stator.

    개시된 환형 구조물을 포함하는 전류고정날개는, 선박의 선미부에서 프로펠러의 전방에 설치되는 것으로, 프로펠러의 회전중심축 둘레에 방사상으로 설치되는 다수의 전류고정날개와, 다수의 전류고정날개의 끝단부들을 둘러싸도록 설치된 환형 구조물을 포함한다. 상기 다수의 전류고정날개는 프로펠러의 회전중심축을 지나는 수직축에 대해 좌우 대칭으로 설치되고, 상기 환형 구조물은 프로펠러의 직경의 40% 내지 60%의 직경을 가지며, 상기 환형 구조물의 코드 길이는 전류고정날개의 끝단부의 코드 길이보다 크다.
