본 발명에 따르면 유체로부터 발생되는 제 1 와류 및 제 2 와류를 상쇄시킴으로써 덕트날개부의 앞전과 뒷전 간의 압력차에 따라 팁 볼텍스 캐비테이션 현상이 발생되는 것을 방지할 수 있으므로, 덕트날개부 및 추진부의 수명을 향상시킬 수 있다.
The present invention is coupled to the main body, the main body being coupled to the ship, to the duct impellers, that the rotation in one rotational direction from the fluid passing through the wing portions to change the direction of flow of the fluid flowing portion propulsion for propelling the vessel claim for forming a second eddy which rotates in the first rotational direction from a fluid passing through a part 1 vortex generator, and wherein the wings are formed on the duct impellers to form a first vortex is formed in the duct impellers a second vortex generator comprises parts of the second vortex generator comprises a first eddy current, and wherein the first and the second eddy current to offset each other the two vortex to occur at a point spaced from the first vortex first vortex generator from relates to a marine stern duct, characterized in that ducts formed in the wing portions apart.
It may, according to the present invention to prevent the tip vortex cavitation according to pressure difference between the leading edge duct wing portion and the trailing edge caused by canceling a first vortex and a second vortex that is generated from the fluid, the duct blade part and driving parts of life It can be improved.
