计算机翼气动力的小程序方便使用，采用涡格法对机翼的升力进行计算，然后可以通过数据分析软件对结果进行拟合，从而得到机翼的升力线斜率。(The small program of the aerodynamic force of the computer is easy to use. The lift of the wing is calculated by the vortex lattice method, and then the results can be fitted by the data analysis software to obtain the slope of the lift line of the wing.)
