Abstract:
(EN) Provided are a duct for a ship, capable of further improving propulsion performance of the ship, and a ship. The duct (20) for a ship has first plate-like body (20a) and a second plate-like body (20b). The first plate-like body (20a) is curved in a circular arc shape having a radius r0, and a cross-section of the first plate-like body (20a) taken in the front-rear direction has an inwardly protruding wing shape. The second plate-like body (20b) is constructed from a flat plate and is provided to an end of the first plate-like body (20a). The distance r between the center axis X1 of the first plate-like body (20a) and the second plate-like body (20b) satisfies the expression of 0 < r/r0 < 0.85.
(FR) L'invention concerne une traversée étanche pour un navire, capable d'améliorer davantage les performances de propulsion du navire, et un navire. La traversée étanche (20) pour un navire comporte un premier corps en forme de plaque (20a) et un second corps en forme de plaque (20b). Le premier corps en forme de plaque (20a) est incurvé dans une forme d'arc circulaire ayant un rayon r0, et une section transversale du premier corps en forme de plaque (20a) vue dans la direction de l'avant vers l'arrière a une forme d'aile saillante vers l'intérieur. Le second corps en forme de plaque (20b) est construit à partir d'une plaque plate et est disposé à une extrémité du premier corps en forme de plaque (20a). La distance r entre l'axe central X1 du premier corps en forme de plaque (20a) et le second corps en forme de plaque (20b) satisfait l'expression de 0 < r/r0 < 0,85.
(JA)  推進性能の更なる向上を図ることが可能な船舶用ダクト及び船舶を提供する。 船舶用ダクト20は、第1板状体20a及び第2板状体20bを備える。第1板状体20aは、半径rを有する円弧状に湾曲されると共に、前後方向における断面形状が内側に向けて突出する翼形状を呈する。第2板状体20bは、平板によって構成され、第1板状体20bの端部に設けられている。第1板状体20aの中心軸X1と第2板状体20bとの直線距離rは、0<r/r<0.85を満たしている。
