摘　　要：介绍了两圆弧绘制圆柱叶片型线的迭代方法。该方法过程简单,方便易行,并克服了传统圆柱叶片型线绘制方法的不足,例如叶片包角不能由设计人员根据需要预先设定等。为圆柱叶片的设计提供了一种新方法。The iterative method of drawing the cylindrical blade profile through two arc is introduced. This method is simple, convenient and feasible, overcoming the disadvantages of the traditional drawing method, for example, the wrapping angle of the blade canJt be predesigned according to the need and so on. A new method for the design of the cylindrical blade is provided.
