A method to optimize propeller performance in ship stern wake has been developed. In the present method, unsteady calculation method of propeller characteristics is used for evaluation of propeller performance in ship stern wake. Real-coded genetic algorithm is used for optimization procedure. Three different objective functions about propeller performance were used for optimization. Improved propellers that have superior performance comparing to original propeller were obtained in each case. In the present calculation, positive correlation between propeller efficiency in uniform flow and propeller performance in ship stern wake was found.

提出了一种船舶尾流中螺旋桨性能优化的方法。本文采用螺旋桨特性的非定常计算方法来评估船舶尾流中螺旋桨的性能。优化过程采用实数编码的遗传算法。采用三种不同的螺旋桨性能目标函数进行优化。在每种情况下都获得了与原始螺旋桨相比具有上级性能的改进螺旋桨。计算结果表明，均匀流中螺旋桨效率与尾流中螺旋桨性能呈正相关。
