摘要
为了使先进空空导弹获得较高的转弯速度以便于实现敏捷转弯,用李亚普诺夫方法分析了姿态稳定以后敏捷导弹的转弯运动特性,并考虑了重力和当地风速的影响。分析结果表明忽略重力和当地风速时,导弹速度矢量必定转动到导弹尖端所指的方向,而且攻角大时转弯速度高,而攻角小时转弯速度低,当存在重力和当地风速时,它们的影响可以忽略。姿态机动仿真结果表明空空导弹利用大角度姿态机动产生了较高的转弯速度从而实现了空空导弹的敏捷转弯。
The turn motion characteristics is analyzed by Lyapunov method with the assumption of stabled attitude for an agile missile to get high turn rates for the agile turn of an advanced air-to-air missile,the effect of gravity and local wind is also considered here.The result shows that the velocity vector of the missile will turn to the orientation the missile nose points to with the effect of the gravity and the local wind ignored.High angle of attack generates high turn rate,and low angle of attack generates low turn rate correspondingly.The result also shows the effect of the gravity and the local wind can be neglected.The attitude maneuver simulation of an advanced air-to-air missile shows that large angle attitude maneuver generates high turn rates,and the agile turn is carried out.
