Energy Analysis in the Explosion Process of High Aluminized Explosive

The shock wave overpressures were measured in explosion field tests for high aluminized explosive and TNT with high resolution and precision.Based on the experimental data and explosion law,the TNT equivalence of shock wave overpressure in explosion field for high aluminized explosive was calculated.The power of aluminized explosive was estimated by TNT equivalence,and the energy inversion principle was applied to assess the reaction extent of combustible components and possible reaction patterns of metal component.It is obtained by calculation that the effective utilization of energy in the aluminized explosive is 65.41%,which provides a new approach for aluminized explosive optimization design.
