研究弹性飞行器的动态耦合问题。首先导出了非定常气动力作用下的弹性飞行器的纵向运动方程。就简化的非定常气动力数学模型提出了分析气动弹性时飞行器稳定性的影响的方法。而后对弹性飞行器的动态耦合特性提出了定性的分析方法。并从有效抑制飞行器的弹性振动角度，研究了主动反馈控制、操纵面及陀螺位置的合适选择的协同设计问题。
Research on Dynamic Coupling of Elastic Vehicles. First, the equations of longitudinal motion of elastic aircraft under unsteady aerodynamic force are derived. A simplified method of unsteady aerodynamic mathematical model is proposed to analyze the influence of aeroelastic stability on aircraft stability. Then the dynamic coupling characteristics of the flexible aircraft proposed qualitative analysis method. And from the perspective of effectively suppressing the elastic vibration of the aircraft, the cooperative design problem of the proper choice of active feedback control, control surface and gyro position is studied.
