机载红外诱饵弹的运动轨迹模型及发展方向

根据红外诱饵出膛后发生燃烧反应的微元体受力数学模型，分析了红外诱饵弹的速度方程，导出了红外诱饵投放后有效持续时间内的速度、诱饵位置、红外质心位置、距载机距离等运动参数的计算公式．对于尾追攻击和迎面攻击两种情况给出了红外诱饵的有效干扰距离与导弹和载机的飞行速度、投放系统的响应时间、红外诱饵的有效持续时间及载机可成功脱离导弹视场角时导弹与飞机最大距离的关系．分析计算结果表明，栽机在系统告警到导弹接近红外诱饵有效干扰距离的时间内应将载机调整到干扰的最佳方位，实现干扰成功的一个要点是载机采取有效的机动措施．还分析了传统红外诱饵进行对抗时存在的问题．提出了分组间隔发射，多个发射器向不同方向投放，采用自燃材料投放后氧化反应形成大面积热云等方法．

Kinetic Trajectory Model and Development Trend of Airborne IR Decoy Flare

Based on the mathematic model of the elements combustion reaction of IR decoy flares ejected from the cartridges,the velocity equations were analysed in this paper,and the algorithm of kinetic parameters,such as flare velocity during the efficient duration time,location,centroid position,distance to the platform etc,was given.The analysis was done,such as IR decoy efficient jamming range,flight speed of the missile and aircraft,reaction time of the dispensing system,decoy efficient burning time and the maximum distance between missile and aircraft when the aircraft has successfully manoeuvred from the missile FOV.in the tail-chasing attack and head-on attack conditions. The results showed that efficient manoeuvring was the most important measure in successful jamming.The disadvantages of traditional IR flare were also analysed,and the new way was introduced,such as firing separately decoys,firing in various direction from multiple dispensers and using self-burning material to form the large scale IR thermal cloud etc.
