摘　　要：球尾线型可以获得桨盘面处周向分布较均匀的伴流，不仅提高了推进效率，取得良好的节能效果，而且可以减少螺旋桨的激振力，从而改善尾部振动。本文以典型的150000DWT苏伊士运河最大船型开发为例，就单球尾艉型的设计，讨论了球尾线型的性能及节能效果，以提供设计者参考。The incorporation of stern bulb on large block coefficient single-screw chip could provide more uniform circumferential wake distribution at pro peller disk. Thus energy-saving effect would be improved by the increase in propulsive efficiency, stern vibration would be reduced by the decrease of pro peller exiting force. To achieve good result, the matching of stern bulb with the aftbody 1ines is of importance. Model test results of three designs with and without stern bulb for Suczmax ship are presented with discussion
