According to the present invention, a rudder with a duct having a Coanda effect includes: a rudder main body in which an inlet is provided on an upper portion; a ring-shaped duct positioned on a lower portion of the inlet in the rudder main body and installed through the rudder main body; and a pressurizing pump installed on the upper portion of the rudder main body and transferring water sucked into the inlet to the ring-shaped duct, wherein the ring-shaped duct is provided with a ring-shaped outlet connected to the inlet through the inside of the rudder main body and discharging the water pressurized by the pressuring pump to the back of the rudder. In the present invention, seawater is sucked in front of the rudder so that the seawater flows out to an inner diameter of the duct. Therefore, the flow of the seawater is quickly formed so that straight moving and turning performance can be improved.
본 발명에 따른 코안다 효과를 갖춘 덕트가 구비된 러더는, 유입구가 상부에 마련된 러더 본체; 러더 본체에서 유입구의 하부에 위치하며, 러더 본체를 통과하면서 설치된 환형 덕트; 및 러더 본체의 상부에 설치되며, 유입구로 흡입된 물을 환형 덕트로 보내는 가압펌프를 포함하며, 환형 덕트는 러더 본체의 내부를 통해 유입구에 연결되며, 가압펌프에 의해 가압된 물을 러더의 후방부로 유출시키는 환형의 유출구가 마련된다. 이러한 본 발명은 러더 전방에서 해수를 흡입하여 덕트 내경으로 해수를 흘려 보냄으로써 해수의 흐름을 빠르게 만들어 직진 성능과 선회 능력을 향상시킬 수 있다.
