为提高综合推进效率，兼顾破冰工况和敞水工况推进需求，针对三桨推进1∶1∶1和1∶2∶1两种功率分配方案，以破冰工况为设计基准开展三桨推进螺旋桨设计，并考虑干扰因子对三桨敞水推进螺旋桨进行优化，对比分析计算结果得出破冰船三桨推进功率分配为1∶2∶1时综合性能更佳。以此确定破冰工况和敞水工况螺旋桨设计参数，为重型破冰船推进系统设计研究提供一定参考。
In order to improve the comprehensive propulsion efficiency and meet the propulsion requirements under ice breaking and open water conditions, the design of propellers is carried out based on the ice breaking condition according to 1∶1∶1 and 1∶2∶1 power distribution scheme of three screw propulsion. The interference factors are considered to optimize propellers under open water propulsion. The results of comparative analysis show the comprehensive propulsion efficiency of 1∶2∶1 power distribution scheme is the better under ice breaking and open water conditions.
