一种新的模拟导弹战斗部破片群单个速度测试系统

A new velocity measuring system for single fragment of simulated missile warhead

介绍了一种用四个改进的天幕靶（ 或光幕靶） 和一台计算机测时系统设计测速系统的方法．利用同一弹丸在弹道上飞过相邻的等距离空间时速度降近似相等的原理，理论推导证明，该系统既可用于测试模拟导弹破片群中每发破片的速度，也可用于测试多管炮（ 枪） 齐射连发时每发弹的速度．

A measuring system for velocity of simulated missile warhead is introduced. It is composed of four improved light screens and one computer multichannel chronometer.Because the velocity decent is constant while a bullet flies throught equal distance,the system not only can be used in measuring the velocity of each of simulated bullets or fragments of missile warhead,but also in measuring the velocity of every bullet during volley and continuous firing of multi barrel gun.
