Measurement of Blast Temperature Field and Study of Thermal Radiation Effect for Thermo-baric Explosive

The infrared imager was used for measuring blasting fireball's temperature of thermo-baric explosive and TNT,and temperature filed of two kinds of explosives were analyzed with the experimental data.Based on the characteristics of thermao-baric explosive and thermal damage rule,combined with Baker's fireball model,thermal radiation effect of thermo-baric explosive and TNT were calculated.Results indicate that thermo-baric explosive is with good thermal damage effect,and average damage radius for death of simulated warhead filled with 20kg thermo-baric explosive is far longer than that of 30kg TNT's.
