Abstract:
(EN) In a ship 1 having a stern duct 10, which is configured to have a duct member 11 and duct support members 12, 13 for supporting this duct member 11 on a ship body 2, disposed immediately in front of a propeller 3, the shape of a rear edge part of the duct member 11 is such that middle connecting sections 11c are provided between an upper arc section 11a and a lower arc section 11b. This configuration provides a ship having a stern duct disposed immediately in front of a propeller in which a thrust generating portion of a stern duct that can generate thrust by using the wake of the ship body can be increased and in which the thrust generated by the stern duct can be improved compared with a circular stern duct.
(FR) Selon la présente invention, dans un navire (1) comportant une traversée étanche de poupe (10), qui est conçue pour comporter un élément de traversée étanche (11) et des éléments de support de traversée étanche (12, 13) destinés à soutenir cet élément de traversée étanche (11) sur un corps de navire (2), disposée immédiatement en face d'une hélice (3), la forme d'une partie de bord arrière de l'élément de traversée étanche (11) est telle que des sections de liaison intermédiaires (11c) sont agencées entre une section d'arc supérieure (11a) et une section d'arc inférieure (11b). Cette configuration fournit un navire comportant une traversée étanche de poupe disposée immédiatement en face d'une hélice, selon lequel une partie de génération de poussée d'une traversée étanche de poupe qui peut générer une poussée à l'aide du sillage du corps de navire peut être augmentée, et selon lequel la poussée générée par la traversée étanche de poupe peut être améliorée par comparaison avec une traversée étanche de poupe circulaire.
(JA) ダクト部材11とこのダクト部材11を船体2に支持するダクト支持部材12、13とを有して構成された船尾ダクト10を、プロペラ3の直前に配置した船舶1において、ダクト部材11の後縁部の形状を上側の円弧部11aと下側の円弧部11bの間に中継ぎ部11cを設けた形状にする。これにより、船尾ダクトをプロペラの直前に配置した船舶において、円形状の船尾ダクトよりも、船体後流を利用して推力を発生できる船尾ダクトの推力発生部分を増加できて、船尾ダクトによる推力を向上できる船舶を提供する。
