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.
