Abstract: The rapid dispersal process and phenomena of high explosive, aluminized explosive and thermobaric explosive were investigated experimentally by using a high-speed framing camera. By comparing the characteristics of the dispersal process and afterburning of the three kinds of explosive, two processes of explosion and afterburn of the thermobaric explosive, and the development history of the afterburn fireball were observed. Based on the experimental results, a formula was proposed to discribe the variation of the dispersal radius of the thermobaric explosive explosion production with time.
