首先导出了在非定常气动力作用下的弹性飞行器纵向运动方程。而后就简化的非定常气动力数学模型提出了分析气动弹性对飞行器稳定性影响的方法。并从有效抑制飞行器的弹性振动角度研究主动反馈控制、操纵面及陀螺位置合适选择的最优综合设计问题。
First, the equations of longitudinal motion of flexible aircraft under unsteady aerodynamic force are derived. Then a simplified unsteady aerodynamic mathematical model is proposed to analyze the influence of aeroelasticity on the stability of the aircraft. From the point of view of effectively suppressing the elastic vibration of the aircraft, this paper studies the optimal integrated design problem with the proper choice of active feedback control, control surface and gyro position.
