Abstract

Abstract

In order to investigate the characteristics of the thermobaric explosives, the 25 g charge of thermobaric explosive was ignited in the sealed explosion chamber of 5.8 L volume, and the explosion pressure and temperature were measured and the gas productions were analyzed by the gas chromatography under the vacuum and air conditions, respectively. The experimental results show that the equilibrium pressure and equilibrium temperature under the air condition are significantly higher than those under the vacuum condition, and the oxygen in the air participates in the oxidation of aluminum, so that there is after-combustion occurring when the thermobaric explosive is ignited in air.
