Abstract
본 발명은 배가 증가된 속도 및/또는 감소된 연료소비로 이동할 수 있도록 배의 추진파도 높이의 감소와 배의 이물(3) 주위의 층류에서의 향상을 성취하는데 사용되는 배(1)의 스템 덕트(2)에 관한 것이다. 이 덕트는 이물전면의 각각의 측면상에 장착되고 그리고 유동방향으로 배열되고 덕트 입구에서의 선단과 그리고 덕트 출구에서의 종단과 끼워 맞춤된 프로펠러 날개부(6)를 가진다. 덕트의 장착에 이어서, 통로(7)는 볼록 프로펠러 날개면으로 이루어진 덕트의 내면과 배의 이물면(3) 사이의 유동을 야기한다. 상기된 통로를 지나가는 유동은 증가된 속도 감소된 압력을 얻어 배의 개량된 운항을 야기한다.The present invention provides a stem duct of a ship 1 used to achieve a reduction in ship propulsion wave height and an improvement in laminar flow around the ship's foreign material 3 so that the ship can move at increased speed and / or reduced fuel consumption. It is about (2). This duct is mounted on each side of the front face of the foreign body and has a propeller blade 6 arranged in the flow direction and fitted with the leading end at the duct inlet and the end at the duct outlet. Following the mounting of the duct, the passage 7 causes a flow between the inner surface of the duct consisting of the convex propeller blade surface and the foreign body surface 3 of the ship. The flow through the passages described above results in increased speed and reduced pressure resulting in improved navigation of the vessel.
