摘　　要：为研究高能化合物FOX-7在发射药中的应用,采用溶剂法制备3种FOX-7含量不同的发射药样品,利用DSC对发射药进行分析,以及密闭爆发器试验,并针对FOX7-3发射药还进行高低常温试验比较。试验结果表明:发射药的热分解与配方中FOX7含量成正比关系,热分解温度随FOX-7含量增加而增高;配方中含FOX-7较高的发射药(FOX7-3),能量较高(火药力为1 030.42 J/g),燃速较快(燃速系数为0.051 6,压力指数为1.066),且燃烧渐增性较好;FOX7-3发射药在高、低、常温下燃烧性能稳定,低温没有出现碎裂的现象。FOX-7在发射药中能够显著提高发射药的火药力,温度系数较稳定,在一定的范围内,通过调整FOX-7的含量能够获得火药力较高和燃烧渐增性较好的发射药。Three gun propellant samples with different content of FOX-7 were prepared by solvent method to investigate the application of FOX-7 in gun propellant. The thermal behavior and combustion property of the propellants containing FOX-7 were studied by DSC and closed bomb test. The closed bomb test of propellant sample FOX7-3 was carried out at high, low, normal temperature respectively. The results show that thermal decomposition temperature of gun propellants containing FOX-7 is proportional to the content of FOX-7. The energy of sample FOX7-3 （with higher content of FOX-7） is higher than others. The burning rate of sample FOX7-3 is faster and burning progressivity is better than others. The burning behavior of sample FOX7-3 under high, low and normal temperature is stable. There is no disintegration phenomenon at low temperature. The specific energy of gun propellant can be increased by adding FOX-7. The temperature coefficient is also stable. By changing the content of FOX-7 in gun propellant, the specific energy of gun propellant can be increased and the burning progressivity can be improved.
