| 摘 要： | 提出了一种分析不对称外挂对飞机颤振影响的方向导数法。该法在原始对称构型的颤振边界曲线已知的情况下，就能推断结构参数不对称时颤振速度的变化趋势。计算实例验证了本文方法的正确性和有效性。

| Abstract: | A direction derivative method for the analysis of the effects of asymmetric stores on flutter speed is presented. The varying tendency of flutter speed can be deduced when the store parameters are asymmetric,according to the results of the original symmetric flutter boundary curves.The correctness and effectiveness of the proposed method are demonstrated by an illustrative example. |

| Keywords: | flutter asymmetric stores direction derivative method |
