Effect of storage temperature on explosion characteristics of RDX-based thermobaric explosive

Abstract The effect of storage temperature on explosion characteristics of the free space explosion of RDX-based thermobaric explosives was studied, and the fireball and the overpressure were obtained. The results showed that the temperature and the volume of the fireball can reach 2400 K and 400 m3 respectively. Low temperature and temperature shock will reduce the temperature and the volume of the fireball and the overpressure. In addition, the aluminum powder does not burn completely, and the time to reach the maximum temperature will be delayed by at least 33 ms. The high temperature can slightly enhance the thermal effect and the pressure effect.
