摘　　要：本文从理论上讨论了不对称前置导管形状的决定方法,并通过数值计算结果讨论了前置导管与螺旋桨间的距离、导管剖面弦线攻角和拱度等对水动力性能的影响,得出了一些具有实际意义的结论。In this paper,methods of deciding the shape of unsymmetrical nozzle are discussed.The theoretical calculations are carried out to investigate into hydrodynamical characteristics of the nozzle in the non—uniform flow field,effects of the distance between the nozzle and the propeller,and also of the attack angle of the chord line and the camber in nozzle sections on hydrodynamical characteristics are analysed basing upon results of numerical calculations,and useful conclusions are drawn as well.
