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。
Due to the structure and aerodynamic layout characteristics of aircraft T-tail, the T-tail flutter calculation can not be applied to the conventional analysis of the tail, but need to consider the impact of flat-tail movement and static lift. Based on the engineering flutter analysis of T-tail, some key problems in the calculation of T-tail flutter are discussed. The characteristics of T-tail flutter and the key parameters affecting the flutter of T-tail are described. Several existing methods of aerodynamic correction in the calculation of flutter of T-tail are put forward the problems that must be paid attention to in the calculation of T-tail flutter engineering.
