摘要:

窄条翼布局导弹通常具有复杂的横向气动特性,在大迎角飞行及快速机动中很容易诱发出现滚转非指令偏离和连续振荡,可能导致飞行失控,影响落点精度。为了研究窄条翼导弹俯仰快速机动对滚转失稳的诱发过程及滚转失稳对俯仰机动控制效果的影响,并验证三通道解耦控制方法的有效性,针对典型俯仰机动过程,分别利用2.4 m跨声速风洞虚拟飞行试验平台和耦合气动/运动/控制的一体化数值计算方法开展了相关研究。结果表明,风洞试验和数值模拟均成功预测了俯仰拉起和保持过程中的滚转自激失稳运动及其引起的纵、横向耦合运动,针对该机动过程,三通道解耦控制方法能够有效抑制滚转运动,保持姿态稳定。

Abstract:

The aerodynamic characteristics in roll of the missile with strake wings are always complicated, which can easily cause the non-directive deviation and oscillation and may lead to losing control of flight and impairing target accuracy. Investigations using the virtual flight testing system in 2.4 m transonic wind tunnel are conducted to study the interplay of roll instability and the longitudinal closed-loop control, and numerical simulation is also performed using the integrative method by aerodynamic/motion/control coupling. The results show that both wind tunnel test and numerical simulation predict the non-directive rolling motion and the pitch/roll coupled motion and prove that the decoupled control method can effectively inhibit the rolling motion and maintain a steady flight.

Key words: missile with strake wings, roll instability, virtual flight, wind tunnel test, numerical simulation, closed-loop control
