The present invention relates to a supporting structure of an oval duct for a ship. An oval duct is installed between a propeller and a stern of a ship. The oval duct includes current fixing wings positioned on the starboard and the port side on a lower side of the center of the propeller. The current fixing wings cross the oval duct in a horizontal direction or are arranged in the oval duct. Therefore, the supporting structure of an oval duct for a ship is configured to obtain driving force from the oval duct and remove a portion in which the current fixing wings are reduced into the rotation energy, thereby increasing propeller efficiency of the ship.

    본 발명은 선박용 타원형 덕트의 지지구조에 관한 것으로, 선미와 프로펠러의 사이에 타원형 덕트가 설치되며, 타원형 덕트에는 프로펠러 중심의 하부 측 좌현과 우현에 위치되는 전류고정날개가 타원형 덕트와 수평방향으로 교차하거나 타원형 덕트 안에 배치됨으로써, 타원형 덕트로부터 추력을 얻고 전류고정날개가 회전에너지로 감소하는 부분을 없애주는 역할을 하도록 구성하여 선박의 추진효율을 높일 수 있다.
