摘　　要：讨论了双桨船和单桨船伴流场的不同特点,给出了双桨船切向伴流的分析方法和不同旋向下的螺旋桨设计结果,指出双桨船适伴流设计考虑切向伴流影响的必要性。内旋设计桨在大型循环水槽中进行了模型试验,试验结果表明螺旋桨的空泡和脉动压力性能优良。Different characteristics of wake fields of single screw ships and twin screw ships are discussed. A method of analyzing tangential wake components for twin screw ships and a design case in different rotational directions are given. The necessity of considering the effect of tangential wake in design of twin screw ship propeller is pointed. Propellers with inward direction design were tested with a whole ship model in a large circulating water channel and the results show that the performance of cavitation and fluctuating pressure of tested propellers is good.
