Computer simulation system of the hydrodynamic performance of the propeller-rudder-rudder bubble combination was built.The hydrodynamic performance computation method of the propeller-rudder-rudder bubble combination was studied,in which the hydrodynamic performance of the propeller was calculated with vortex lattice method,while the influence of the hub to the hydrodynamic performance of the propeller was calculated with Hess-Smith boundary element method.For thinking about the influence of the rudder and rudder bubble,the velocities induced by the rudder and rudder bubble was regarded as correction of the velocity of the incoming flow of the propeller and hub.Computer simulation system was used to design and simulate four kinds of propeller-rudder-rudder bubble combination,then the comparison with the computation result of the original propeller-rudder design was carried out.It is shown that the designed rudder bubbles can increase the efficiency of propeller obviously,in which the dissymmetric rudder bubbleachieves energy-saving effect 5.1% and increases the power reserve of main engine up to 5% in real boat test.

建立了螺旋桨—舵—舵球推进组合体水动力性能的计算机仿真系统。系统研究了螺旋桨—舵—舵球推进组合体水动力性能的计算方法,建立了相关的仿真数学模型。模型中螺旋桨的水动力性能采用升力面理论涡格法计算,桨毂的影响采用Hess-Smith面元法计算。将舵及舵球的诱导速度作为对桨及桨毂进流的修正,以考查舵及舵球的影响。舵与舵球水动力的计算采用以速度势定义的面元法。在此基础上,进行系统功能设计,编制了计算机仿真系统。应用此软件设计了四种舵球方案,并进行了相应方案螺旋桨的定常水动力性能的计算对比分析。仿真计算表明,设计的舵球方案可有效地提高螺旋桨的水动力性能。其中不对称型舵球方案在实船对比测试中获得了节能5.1%,提高主机功率储备5%以上的效果。
