Open publisher page 2 citations

Abstract

The air explosion experiment is done by adding AP in composite explosives based HMX and RDX and aluminized explosives respectively,to study the effect of AP on the performances of air explosion.The influence of AP on the air explosion parameters from the shock wave overpressure,the maximum radius and the duration time of fireball and the explosion field temperature is analyzed.The results show that AP can affect shock wave overpressure of air explosion but the influence trend is related to different main explosive.For composite explosives based HMX and RDX,AP can made the shock wave overpressure decrease,while for aluminized explosive,AP can made the shock wave overpressure increase,but for the two kinds of explosives,with the increase of AP,the maximum radius and the duration time of fireball and the explosion field temperature are all decreased.
