The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory. the blade geometry is expressed with b - spline for the lift - surface method. the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities, the fair blade geometry can be obtained by present technique and the design quality is better
改進了現有的升力線和升力面設計方法，在升力線設計中計及槳葉的縱傾和側斜的影響，用優化理論求解最佳環量分佈，升力面設計中用b樣條來擬合槳葉，將物面邊界條件轉化為求法向速度分量的平方最小，由此可得到光順的槳葉幾何形狀，提高和改進了設計質量。
