二级轻气炮弹速激光测量系统

System utilizing laser diode for two-stage light gas-gun projectile velocity measurement

介绍了激光测速法在二级轻气炮弹丸速度研究中的应用。为了满足对二级轻气炮毫米级弹丸速度高精度测量的需求,采用激光光束遮断法,研制了毫米级弹丸片状激光测量系统,系统主要包括发射端和接收端两个部分。整个系统可安装于二级轻气炮的炮管延长段,结构紧凑、抗干扰、有效测量范围大,可作为高速弹丸速度测量手段。应用该系统进行了模拟测速实验和二级轻气炮弹丸现场测速实验,并给出了典型测速实验结果。

A new system utilizing laser was set up , which can be used to measure two-stage light gas-gun projectile velocity. The system consists of two parts, which are project system and incept system. The system was integrated in the barrel extension of two-stage light gas-gun. It not only has the advantages of simple structure and anti-jamming but also has wide range of measurement. The simulation experiments were performed and the system was used successfully to measure the projectile flight velocity of two-stag...
