应用比色测温仪测量燃料空气炸药爆炸过程温度响应

Research on the Explosive Temperature Response of Fuel Air Explosive Measured by Colorimetric Thermometer

基于光辐射原理,建立了红外比色辐射高温测量系统并对燃料空气炸药分散爆轰过程中的温度响应进行了实时测量,得到了一次引爆型燃料空气炸药和二次起爆型燃料空气炸药爆炸的温度响应,并对两种不同型式的燃料空气炸药的爆炸温度场及其特点进行了对比分析。结果表明,与二次引爆型燃料空气炸药爆炸相比,一次引爆型燃料空气炸药爆炸的最高温度较高,持续时间较长。

A infrared colorimetric radiation high temperature measurement system was established based On the theory of light radiation. The dynamic temperature history of fuel air explosive was measured to obtain the temperature responses of single event and double event fuel air explosives in real time, and the characteristics of their temperature history curves were compared and analyzed. The compared and analyzed results show that the maximum temperature of the single event fuel air explosive is higher than that of the double event fuel air explosive, and the high temperature druation of the single event fuel air explosive is longer than that of the double event fuel air explosive.
