摘　　要：为研究铝粉在HMX基炸药中的能量释放特性,采用压力传感器对不含铝粉的HMX/HTPB 88/12炸药及含有粒度为13,130μm铝粉的HMX/Al/HTPB 53/35/12炸药在密闭空间中爆炸后的准静态压力进行了测量。结果表明:HMX/HTPB 88/12和HMX/Al/HTPB 53/35/12炸药爆炸后在密闭条件下均能产生准静态压力。HMX/Al/HTPB 53/35/12炸药的准静态压力是HMX/HTPB 88/12炸药的1.24倍。铝粉颗粒度分别是13μm和130μm的HMX/Al/HTPB 53/35/12-炸药在密闭空间中爆炸产生的准静态压力分别是378 k Pa和347 k Pa,说明内爆条件下,当铝粉含量为35%时,与含大颗粒铝粉炸药相比,含小粒度铝粉炸药能够释放更多能量,提高密闭空间中的准静态压力。To study the energy releasing characteristics of aluminum powder in HMX based explosives,the quasi-static pressure of HMX / HTPB 88 /12 and HMX / Al / HTPB 53 /35 /12 explosives containing aluminum powder with granularity of 13 μm and 130 μm respectively after explosion in an enclosed space was measured by pressure sensor. Results show that the quasi-static pressure after explosion of HMX / HTPB88 /12 and HMX / Al / HTPB 53 /35 /12 explosives in an enclosed condition can be produced. The quasi-static pressure of the HMX / Al / HTPB 53 /35 /12 explosive is 1. 24 times greater than that of the HMX / HTPB 88 /12 explosive. The quasi-static pressure of HMX / Al / HTPB 53 /35 /12 explosives containing aluminum powder with granularity of 13 μm and 130 μm respectively,produced by explosion in an enclosed space is 378 k Pa and 347 k Pa,respectively,meaning that under implosion condition when the content of aluminum powder is 35%,compared with the explosive with the large particle aluminum powers,the explosive with small particle aluminum powder can release more energy and improve the quasi-static pressure in an enclosed space.
