Abstract:
(EN) A ship propulsion device, wherein an attachment 4 for reducing the hub vortex of a propeller 2 is installed at the elevation of the propeller 2 on the front edge of a rudder 3 disposed at the rear of the propeller 2. The distance L1 between the front edge of the rudder 3 and the blade center of the propeller 2 is 30-60% inclusive of the diameter D of the propeller 2. The distance L2 between the front end of the attachment 4 and the rear end of the propeller 2 is within the range of 50-300 mm.
(FR) La présente invention concerne un dispositif de propulsion de navire, dans lequel un accessoire 4 pour réduire le tourbillon de moyeu d'une hélice 2 est installé au niveau de l'élévation de l'hélice 2 sur le bord avant d'un gouvernail 3 disposé à l'arrière de l'hélice 2. La distance L1 entre le bord avant du gouvernail 3 et le centre de la pale de l'hélice 2 est de 30 à 60 % inclus du diamètre D de l'hélice 2. La distance L2 entre l'extrémité avant de l'accessoire 4 et l'extrémité arrière de l'hélice 2 est comprise entre 50 et 300 mm.
(JA) プロペラ2の後方に配した舵3の前縁におけるプロペラ2の高さ位置に、プロペラ2のハブ渦を低減するための付加物4を設置する。舵3の前縁とプロペラ2の翼中心との距離L1はプロペラ2の径Dの30%以上60%以下とし、付加物4の前端とプロペラ2の後端との距離L2は50mm以上300mm以下とする。
