摘要
提出了一种计算带制流板舵在螺旋桨尾流中水动力性能的方法．舵的水动力及周围流场用面元法计算，螺旋桨性能及尾流场通过无限叶数的简易螺旋桨理论来预估，而舵上下制流板的影响则应用升力面理论的涡格法来计算．舵、制流板、螺旋桨的干扰作用以迭代方法求得．由于采用了面元法，舵的水动力性能及表面压力分布的计算更为精确．文中还对带制流板舵的操纵性能进行了计算和研讨．计算结果与实验值比较，吻合程度良好．
A new method for predicting the hydrodynamic performance of the rudder with plates behind a propeller is presented. The hydrodynamics of the rudder body is calculated by the panel method, the influence of the plates is calculated by the vortex lattice method, and the performance of the propeller is predicted by the simple propeller theory. The interactions among the rudder body, plates and propeller are determined by iterative procedure. The calculated results are compared with the experimental data and the agreement is satisfactory.
