摘　　要：以奇点分布设计轴流叶片翼型时 ,必须计算初始翼型骨线部分给定点上的诱导速度。由于问题的复杂性和落后的计算手段 ,传统计算中仅能以使用已久的简化方法计算骨线上几个有限点处的速度值。本文作者给出的新方法中 ,以MATLAB软件编程算速度值 ,计算点增多到任意多个 ,从而有效提高了最终骨线精度 ,为这类翼型设计提供了一新途径。A design program for axial flow impellers singularity distribu ti on methodology was usually adopted in design practice When this method is used , the induced velocity at a prescribed point s 0 on the mean line of the basic plate is required to be worked out In the traditional way ,because of the complexity o f the equations and the backward method only seven points on the basic plate can be dealt with This paper addresses an improved approach to the program in achi e ving more accurate results in the design stage By offering a MATLAB program,as many points as reguired on the basic plate can be calculated Besides, much mo r e cylindrical surfaces can be calculated within a short time period This means more accurate results can be achieved and pump efficiency will thus be improved
