为比较含铝炸药与一次引爆燃料空气炸药(FAE)威力特性,对JHL-2含铝炸药与一次引爆某燃料空气炸药公斤级爆炸冲击波参数进行了测试.结果表明,在相同装药体积情况下,距爆源水平距离为3 m、5 m和7 m处,JHL-2冲击波峰值超压比一次引爆某燃料空气炸药分别提高了13.5%、39.0%和18.5%,正压区冲量提高了21.5%、22.7%和16.5%,正压作用时间略有下降,说明含铝炸药爆炸威力可以达到甚至超过一次引爆FAE.
為比較含鋁炸藥與一次引爆燃料空氣炸藥(FAE)威力特性,對JHL-2含鋁炸藥與一次引爆某燃料空氣炸藥公斤級爆炸遲擊波參數進行瞭測試.結果錶明,在相同裝藥體積情況下,距爆源水平距離為3 m、5 m和7 m處,JHL-2遲擊波峰值超壓比一次引爆某燃料空氣炸藥分彆提高瞭13.5%、39.0%和18.5%,正壓區遲量提高瞭21.5%、22.7%和16.5%,正壓作用時間略有下降,說明含鋁炸藥爆炸威力可以達到甚至超過一次引爆FAE.

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.
