摘　　要：通过船、机、桨三者之间关系的分析 ,将实测的柴油机带动螺旋桨的推进特性放入主机功率允许工作区域图中 ,从而判断 2 1 60kW海洋救助拖船螺旋桨选配设计不合理。按拖轮使用的主要工况考虑一定的储备 ,削边修正螺旋桨 ,使船舶主机长期安全营运。By putting the propulsion performance curve of the dieseldriven propeller on ME's permissible working power area and analyzing the relationship among the ship,ME & propeller,a judgement was formed that the selection and design of the propeller for a salvage tug of 2160 kW was not suitable.According to the tug's main working conditions and the power reserve,the propeller was corrected through machining its tip part,the ship ME runs long and safely.
