摘　　要：通过试验和理论计算,研究导管内螺旋桨前后加支撑筋对特殊导管桨的水动力性能影响,重点讨论导管内桨后支撑筋的叶片数和安装角对水动力性能的影响。结果表明,由于该导管桨的特殊性使得其效果与一般导管桨不同。The influences of the supporting tendons installed before and after the propeller in duct on the hydrodynamic performance to the special ducted propeller had been researched. By experiments and theoretical calculation, the influences of blades number and install angle of the support tendons after propeller were discussed mainly. The results indicated that the effect of this ducted propeller is different from common ducted propeller because of its particularity.
