Title       Measurement of Afterburning Fireball   Parameters of Aluminized Explosives         

Abstract In this paper, the measurement of the parameters, the influence factors and the thermal radiation effect of aluminized explosive afterburning fireball were studied. The measurement methods of the temperature, size and duration of afterburning fireball were introduced. Based on the radiation of Al2O3, the fiber multi- wavelength thermometry system was established，and the system was calibrated. Both the deficiency of the old system and the improvement of the new one were discussed. According to the experimental measurement, the effects of explosive composition on the form of fireball were analyzed. On the basis of the experimental results, the dynamic model of thermal radiation was used to calculate the thermal radiation effect. Compared with the Baker model, the dynamic model could be more reasonable.
