Detonation temperature of thermobaric explosives

The infrared thermography method was used to investigate the detonation temperature of thermobaric explosives (TBE). The experimental result shows that the temperature of TBEs detonation cloud is higher than that of TNT with the same weight. The duration of high temperature and the volume of the high temperature cloud are 2~5 and 2~10 times as much as those of TNT, respectively. This implies that TBE is superior to the traditional high explosive on the temperature field. The high-temperature environment formed by the explosive explosion is sufficient to maintain the afterburning of the aluminum powder，which can provide assistance to boost up the blast wave.
