直接的方法是基于设计逐案分析的方法是机翼形状指定第一。

Direct methods are based on the design-by-analysis approach in which the airfoil shape is specified first.

因此，它会更有利，指明速度分布，从一开始就确定，从机翼形状。

Thus, it would be more advantageous to specify the velocity distribution from the outset and from that determine the airfoil shape.
