According to the present invention, a ducted fan comprises: a duct having a circular internal side circumference surface; and a propeller mounted on an inner side of the duct to be rotated. The present invention relates to a ducted fan with a plurality of vortex generating means which is not influenced by rotation of the propeller in an internal side circumference surface of the duct, and specifically, relates to a ducted fan with a vortex generating means, wherein a vortex generating means is installed in an area wherein moving desquamation may be greatly generated in an internal surface of the duct to delay moving desquamation for ducted fan efficiency of lift, thrust, or the like to be improved.

    본 발명은 원형의 내측 둘레면을 갖는 덕트 및 상기 덕트의 내측에 구비되어 회전하는 프로펠러를 포함하여 이루어진 덕티드 팬에 있어서, 상기 덕트의 내측 둘레면에는 상기 프로펠러의 회전에 간섭되지 않는 다수 개의 와류발생수단이 구비된 덕티드 팬에 관한 것으로써, 특히, 덕트 내부 표면에서 유동 박리가 크게 일어날 수 있는 영역에 와류발생수단을 설치하여 유동 박리를 지연시켜 양력 및 추력 등의 덕티드 팬 효율을 향상시킬 수 있는 와류발생수단이 구비된 덕티드 팬에 관한 것이다.
