Blast power of JHL-2 aluminized explosive and a single-event fuel air explosion (FAE) was compared. Two types of explosives were kilogram-level charged and pressure-time curves of shock wave at 3 m, 5 m and 7 m away from explosion center were obtained. Results show that when the charged volumes are the same,the peak pressures of JHL-2 are increased by 13.5%,39.0% and 18.5% higher than that of the single-event FAE at 3 m, 5 m and 7 m away from explosion center respectively,and the positive phases of JHL-2 are increased by 21.5%,22.7% and 16.5% higher than that of the single-event FAE,while the positive phase durations of JHL-2 are shorter than that of the single-event FAE. Results show that blast power of aluminized explosive can achieve and even overtake that of single-event FAE.
