摘　　要：在平头涡尾船型研究的基础上，将内河双涡尾拓展到单桨海船上，提出一种单涡尾船型．该船型仅改造母型船尾柱向首设计水线以下１５％ＬＷＬ左右的区域，不影响原船的机舱布置和舱容．船模试验表明该船型具有与常规船相当的阻力性能和优秀的推进性能，可节省主机功率１２．５％～２８．８％．A vortex flow stern for single screw ship is presented, based on study results of flat bow and Cochlea channeled stern. The single vortex flow stern shipform, which is obtained by modifying stern hull lines of about 15% L WL range under designed waterline from A. P. to P.P., has no effect on engine room arrangement and cabin capacity of the original ship. Model tests indicate that the ship with single vortex flow stern has basically the same resistance performance and better propulsion performance compared with traditional shipform, and can save power of 12.5 %～28.8 %.
