【摘要】 研制了一种剖面形状呈鱼形，能控制与改变螺旋桨艉流方向的高性能舵，该仿生鱼形舵的流体动力特性好。装备该舵的船舶，小舵角时，升力系数高，船舶操纵性好，适用航行于险航区；大舵角时（大于３５°以上）．即可向两舷转动７０°把推力方向改变成与船体成９０°方向，船艉获得较大侧向力，实现船舶原地回转，改善了低速航行时的操纵性。更多还原

【Abstract】 A high performance rudder with a profile likethat of a fish has been developed.The di-rection of the slipstream of the propeller can be adjusted and the hydrodynamic characteristicof the rudder is good.Test results show that if a ship is equipped with such a rudder,the liftcoefficient will be great at a small rudder angle and the maneuverability will also be good indangerous water courses.At a large rudder angle(>35°),the rudder can be rotated 70°inboth directions. This will provide a large lateral force as the thrust provided by the main en-gine can be varied to fOrm an angle of 90 deg with the hull. In this case, the ship will turnround itself in situ,thus improving the maneuverability of the ship at low speed.更多还原
