| 摘 要： | 根据桨舵干扰思想，采用以速度势为基础的低阶面元法计算了均匀流中的螺旋桨与舵 舵球 鳍系统相互干扰的定常水动力性能，比较了普通舵及加装舵球、舵球鳍的舵的节能效果，并对影响舵球鳍节能效果的主要参数(舵球尺寸、鳍片尺寸和安装角度)进行了变尺度计算与分析. 计算结果表明，舵球鳍节能效果较舵球为佳，并具有节能效果最佳的尺寸及安装角度.

| Abstract: | Rudder-bulb-fin is a kind of simple combined energy-saving device.According to the method of propeller-rudder system performance calculation,the steady interference between propeller and rudder-bulb-fin system in uniform flow was predicted by potential based surface panel method.The energy-saving effect of rudder with bulb-fin was compared with common rudder and rudder with bulb.Changing dimensions,the principal parameters(bulb size,fin size and installation angle) that affect energy-saving effect was studied.The theoretical studies show that the energy-saving effect of rudder-bulb-fin is better than that of rudder-bulb and the design of rudder-bulb-fin has optimal bulb size,fin size and installation angle. |
