The design process of the test-bed of the low speed airfoillift-drag force characteristic was introduced, and the experimental results of the airfoil were analyzed.

Optical lift is different from the aerodynamic lift created by an airfoil.
光学提拉力与机翼翼面产生的空气动力不同。

The stall of the wing occurs at the highest lift coefficient on an airfoil, when the airflow can no longer go around the airfoil's nose (leading edge) and separates from the upper wing surface.
