From the angles of the disign of the profile of the wing surface of an aircraft, a simple method is derived for solving the profile of the oblique section of wing surface, using the interrelation between the length of chord of the section in the same direction as airflow and that of arbitrary oblique section in this paper.

这对于求解着于非顺气流方向的翼肋外形来说，尤其显得方便。
