摘要
弹射类火工装置需要测量其出口速度,但由于火工装置的动态冲击特性常难以获得稳定可靠的数据。文中介绍了一种光电测速系统,它具有非接触测量、动态响应好等优点。经过试验验证可以用于火工装置的测试。
Because of the dynamic shock characteristics in ejection type of pyrotechnics, the outlet velocity of pyrotechnics is difficult to measure, stable and reliable data is difficult to be obtainld. This paper introduces a photoelectric velocity measuring system, it has more advantages, such as non-contact measurement, good dynamic despondence and so on. It is proven that the system can be used in tests of pyrotechnics.
