摘　　要：给出了第三代平头涡尾船型的船模阻力、船模自航试验结果和实船测速结果，通过试验分析，阐述了该代船型具有优异的推进性能并对其机理作了探讨．讨论了伴流分数及推力减额系数对推进效率的作用．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 %.
