The present invention relates to a fluid resistance reducing apparatus for a ship, and more specifically, to a fluid resistance reducing apparatus for a ship which greatly reduces a friction resistance and a wave resistance by seawater when the ship sails, thereby implementing speed improvement, stable sailing, and fuel saving. According to the present invention, the fluid resistance reducing apparatus is provided below a draft line of a hull. The seawater is introduced into a bow portion to be discharged to the back of the stern by using a rotating operation of a propulsion propeller provided on the hull. Therefore, the friction resistance and the wave resistance of the seawater can be greatly reduced so that improvement of a sailing capacity, an improvement in speed, and a fuel saving effect can be implemented.

    본 발명은 선박의 유체 저항 저감장치에 관한 것으로서, 보다 상세하게는 선박이 항해할 때 해수에 의한 마찰저항과 더불어 조파저항을 크게 줄여 속도 향상과 함께 안정적인 항해 및 연료 절감을 구현할 수 있는 선박의 유체 저항 저감장치에 관한 것이다.본 발명에 의하면,선체의 흘수선 아래로 유체 저항 저감장치가 구비되어지되, 선체에 구비되는 추진 프로펠러의 회전 작동을 이용하여 선수부분에서 해수를 유입하여 선미 후방으로 배출토록 하면서 진행할 수 있도록 함으로써 해수의 마찰저항 및 조파저항을 크게 저감시킬 수 있어, 운항능력 향상은 물론이고 속도 향상 및 연료 절감 효과를 구현할 수 있도록 한 효과를 나타낸다.
