Due to complicated configuration and multi control surfaces,the flutter characteristic design of T-tail is complicated and there are many parameters in the process of establishing dynamics finite element model,so the designers face more difficulties.

• T型尾翼构型复杂；操纵面多；在动气动弹性的有限元建模和颤振特性设计中；需要修改的参数多；颤振分析复杂；设计人员面临很大的困难.
