(EN) PROPELLER WAKE FLOW STRAIGHTENER DEVICE
(FR) DISPOSITIF POUR RENDRE LINÉAIRE UN ÉCOULEMENT DE SILLAGE D'HÉLICE
(JA) プロペラ後流整流装置
Abstract
(EN) The present invention is an invention of a propeller wake flow straightener device, in particular, an invention of a rudder horn that is installed posterior to a propeller of a ship and swingably supports a rudder. A streamlined bulge section (14) is formed over sidewall surfaces of the rudder horn at a position on an extended line from the propeller axis.
(FR) La présente invention porte sur un dispositif pour rendre linéaire un écoulement de sillage d'hélice, et, en particulier, sur une trompe de gouvernail qui est installée à l'arrière d'une hélice d'un navire et qui porte de façon oscillante un gouvernail. Une section de renflement carénée (14) est formée sur des surfaces de paroi latérale de la trompe de gouvernail dans une position sur une ligne de prolongement à partir de l'axe de l'hélice.
(JA)  本発明は、プロペラ後流整流装置の発明であって、特に、船体のプロペラの後方に配置され、方向舵を揺動可能に支持するラダーホーンに関する発明である。ラダーホーンのプロペラ軸の延長線上における側壁面に、流線型の膨出部14を形成した。
