便携式红外寻的导弹近炸引信延迟引爆时间的研究

Research on proximity detonated fuse delay time of portable infrared homing seeker missile

为提高便携式红外寻的防空导弹攻击小目标的能力,采用近炸引信是非常必要的。而导弹的近炸引信探测装置一般在碰撞目标前即已启动,因此只有设置合适的延迟起爆时间,才能使战斗部尽可能多的破片击中目标,以获得最佳的杀伤效果,提高对目标的杀伤概率。通过对近炸引信启动与引战配合进行数学建模,采用蒙特卡洛法进行仿真计算,获取迎攻和尾追状态下近炸引信引爆延迟时间与击中目标破片数量的关系,以确定最佳引爆延迟时间。

In order to enhance the attacking ability of portable infrared homing air-defense missile for the small targets,it is necessary to use the proximity fuse.The missile＇s proximity fuse detector generally starts before colliding the targets,therefore only by setting the appropriate delay detonated time,the warhead can shoot targets with as many broken pieces as possible and obtain the best fragmentation effect and the target-kill probability.The mathematics modeling was carried out for the proximity detonated fuse starting and the matching between fuze and warhead,the Monte-Carlo algorithm was employed to carry on the simulation computation,so as to gain the quantity relations of the proximity fuse detonation delay time and the number of shoot-goal broken piece under the attacking and pursuing condition,then to determine the best detonation delay time.
