摘要

摘要: 对双尾撑布局飞机进行飞行载荷和气动导数分析,重点分析尾撑纵向弯曲刚度和飞行动压变化,对纵向气动力导数、各操纵面效率以及载荷分布的影响.尾撑纵向弯曲刚度变化会引起纵向静稳定性、平尾升降舵的操纵效率及反效速度、平尾的载荷分布的显著改变.尾段刚度尤其是尾撑的纵向弯曲刚度往往会构成双尾撑布局飞机气动弹性设计的薄弱环节,在设计时应该严格控制尾撑的刚度指标.

Abstract: Flight loads and aerodynamic derivative analysis of a twin-tailboom aircraft was performed. The longitudinal aerodynamic derivative, the efficiency of each control surface and the load distribution were considered emphatically, as a function of the tailboom stiffness of longitudinal bend and the flight dynamic pressure. The tailboom stiffness of longitudinal bend has quite an effect on the longitudinal static stability, the efficiency and anti-efficiency speed of the elevator on the horizontal tail, even the load distribution of the horizontal tail. The stiffness of the tail section, especially the tailboom stiffness of longitudinal bend, uasually causes the weakness, as the aeroelastic analysis is processing on a twin-tailboom aircraft. The design standard of the tailboom stiffness must be controlled strictly.
