| 摘 要： | 本文提出了一种亚音速、完全非定常机翼气动力的数值计算方法（暂称为“势差法”）,该方法对于机翼所作的任意运动,能在时间域内计算出气动力和空间速度场的变化规律。算例结果表明势差法计算结果与其它方法计算结果和实验值是一致的。

| Abstract: | A new numerical method, the velocity potential difference method, is developed in this work for predicting the aerodynamic force of fully unsteady wings in subsonic flow. The method is capable of computing the varying aerodynamic force or velocity field in time domain over wings with arbitrary motion. The computed results of some test cases are compared with those of other computational methods and experiments, and are found to be in good agreement. |
