T型尾翼是一种特殊的翼面布局形式,由垂尾和布置于垂尾翼尖的平尾组成。此布局由于平尾位置较高,在小攻角飞行时能够使其避开机翼下洗区,同时尾臂长度增加,提高了平尾的操纵效率和尾翼的气动效率。另外,T型尾翼构型利于实现后机身大开口,方便了货物装运。因此,许多大型军用运输机和尾吊发动机布局的民用客机都选择T型尾翼布局。作为翼面结构,T型尾翼也具有传统弯扭耦合的颤振特性。传统翼面结构颤振特性分析一般采用偶极子网格法 The T-tail is a special form of airfoil that consists of a tail and a flat tail arranged at the tip of a tail. Due to its high flat tail position, this layout avoids the wing wash zone at low angle of attack and increases the length of the tail boom, improving the handling efficiency of the tail and the aerodynamic efficiency of the tail. In addition, T-shaped tail configuration is conducive to the realization of a large fuselage opening to facilitate the shipment of goods. As a result, many large commercial transport aircraft and tail-hang engine layout of civil passenger aircraft have chosen T-tail layout. As an airfoil, the T-tail also has the traditional flutter-coupled flutter characteristics. The traditional analysis of flutter characteristics of airfoil structure using dipole grid method
