传统狭缝摄影测量弹丸转速的方法,对于弹体较小、转速较低的情况存在较大误差。对此提出了一种新的狭缝摄影测量弹丸转速的方法,相对于传统方法,狭缝摄影机数量由一台变为两台。对测量精度分析表明,与传统方法相比,该方法测量精度提高10倍以上,满足了低转速导弹测试精度要求。

Obvious error always occur by using traditional slit photography measuring rotation velocity of projectile with small volume or low rotation speed, so a new method on measuring rotation velocity of projectile was proposed. Compared with traditional method, the number of slit camera should be raised as two instead of one. The measuring accuracy analysis demonstrates that the precision has been improved 10 times compared with that got by traditional method and meets the requirement of test accuracy of missile with low rotation speed.
