基于建模仿真的飞机桶滚机动规避空空导弹效果及原因分析

基于飞机桶滚机动规避空空导弹攻击的作战背景,建立了导弹与飞机的空间交会模型。以导弹脱靶量、过载以及舵偏角速率为依据,对桶滚机动不同机动时机、周期下的规避效果以及规避原因进行了仿真分析。研究结果表明,导弹脱靶量与机动时机的关联性较弱,可随着机动周期的增大而减小。当机动周期为 2~3 s时,导弹脱靶量较大,飞机规避效果较好。飞机桶滚机动规避导弹的原因不仅在于导弹交会过程中过载的增大,而且还在于导弹交会过程中舵偏角速率的增大。

Effect and Reason Analysis for Aircraft Barrel Roll Avoiding Air-to-Air Missile Based on Modeling Simulations

Based on the combat background of aircraft barrel roll avoiding air-to-air missile attack, the space intersectionmodel of missile and aircraft is established. Based on the miss distance, overload and rudder deviation rate of the missile,the avoidance effect and avoidance reasons for barrel roll under different maneuver timings and periods are analyzed. The re.sults show that the correlation between miss distance and maneuver timing is weak. However, the miss distance decreaseswith the maneuver period increasing. When the maneuver period is 2~3 s, the miss distance is large and the aircraft avoid.ance effect is good. The reason for barrel roll avoiding the missile is not only the increase of the missile overload in the en.gagement process but also the increase of the missile rudder deviation rate in the engagement process.
