摘要
狭缝联动摄影外弹道测试基础系统采用多台狭缝高速摄影机联动方式对飞行弹丸的速度、自旋速率、章动角及偏航等外弹道参数进行综合测量。它经过严格的空间位置标定,具有统一的时间基准,由微机控制实现对各摄影机的实时控制。大量试验表明,该系统对飞行弹丸测速精度为千分之一;自旋速率测量误差小于百分之一;章动角测量误差为6[角]分,偏航误差为1.5毫米。
Multi-synchro-ballistic cameras have been introduced to measure the flying bullet velocity, spin rate, attack angle, yaw and so on, which are important exterior ballistic paramaters. Spatial positions have been strictly located, and unified time criterion has been established. The basic system is real-time controlled by microcomputer. By means of experiments and analyses, it has been proven that the velocity measuring accuracy achieves zero point one percent; the spin rate measuring error is less than one percent the attack angle error is six minutes; and the yaw error is one point five millimeter.
