| 摘 要： | 本文提供了一个精确表达式,通过它可将亚声速位势流动仿射变换成不可压缩流动。同时给出了新的气动力计算公式。在流过Joukovski翼型的气动力计算中,它与用计算机提供的精确数值计算结果相比较,二者很符合。

| Abstract: | This paper derives an exact expression which changes the potential subsonic flow into the imcompressible flow through an affine transformation. Meanwhile, presents a new formula of the aerodynamic force evaluation. Compared with the exact numerical solution proposed by computer, the agreement between the formula and the numerical solution for flow over a joukovski profile is very good. |
