Research on the explosive temperature response of fuel air explosive measured by colorimetric thermometer

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 duration of the single event fuel air explosive is longer than that of the double event fuel air explosive.
