飞机T型尾翼颤振计算的若干关键问题

摘要 由于飞机T型尾翼的结构与气动布局特点，T型尾翼颤振计算不能套用常规尾翼的分析方法，而需要考虑平尾面内运动以及静升力等因素的影响。从T型尾翼的工程颤振分析出发，讨论了T型尾翼颤振计算中的若干关键问题，阐述了T型尾翼颤振特性的特点和影响T型尾翼颤振特性的关键参数，分别介绍了现有的几种T型尾翼颤振计算中的气动力修正方法，提出了T型尾翼颤振工程计算中必须注意的问题。

Some key issues of aircraft T-Tail flutter calculation

The flutter calculation method for convensional aircraft tail wing can not be used directly to T-tail flutter analysis due to T-Tail features in structural and aerodynamic configurations,and the effects of in-plane motion and steady aerodynamic force of horizontal plane must be considered in T-tail flutter calculation.From the view point of engineering analysis for T-tail flutter,some key issues of T-tail flutter calculation were discussed here,the characteristics of T-tail flutter problem and the key param...
