| 摘 要： | 本文给出一种计算飞机机翼上定常和非定常跨音速气动力的数值解法,使用了一种特殊设计的坐标变换,是用时间精确交替方向隐式(ADI)有限差分算法来求解非定常跨音速修正三元小扰动位势方程。给出了F5战斗机机翼的数值结果并与XTRAN3S,ATRAN3S及试验结果进行了比较,表明本方法是有效的和经济的。

| Abstract: | A numerical method is presented for predicting steady and unsteadytransonic aerodynamic flow about aircraft wing configuration. A special designed coordinate transformation is employed in the method. The numerical procedure solves the unsteady transonic modified three-dimensional small perturbation equation by time accurate alternating direction implicit finite difference algorithm. Numerical results are presented for an F-5 fighter wing and compared with experimental data for transonic flight conditions. |
