复合分散药的性能及对FAE燃料分散的影响

Controlling Fuel Dispersion of FAE by Combination Burster

设计了一种新型结构的复合分散药,用以取代常规燃料空气炸药(FAE)分散药,对复合分散药爆轰波传播模型、装药结构尺寸、芯药和外层炸药爆速、复合分散药占燃料质量分数对FAE爆炸云雾的形成和传播进行了分析研究。在此基础上,进行了以压装密度为1.72 g.cm-3、爆速为8400 m.s-1的8701炸药为芯药,以低密度硝基胍(NQ)为外层炸药,以环氧丙烷(PO)和宏观固态燃料为FAE燃料分散与引爆实验。结果表明,采用复合分散药,分散药燃料比超过1.3%,云雾未发生窜火,云雾形状基本为类草帽形,并可靠爆轰,这说明采取复合装药结构是完全可行的。

To substitute the general burster used in FAE bomb,the new combination burster is designed. The fuel dispersion of the FAE bomb is analyzed on the detonation wave and the charge dimension and the detonation velocity and the burster-fuel weight ratio of the combination burster. Moreover,the fuel dispersion and the FAE cloud ignition were experimented under the condition of the PO fuel or the maeroseopieal solid fuel and the combination burster made of the high detonation velocity explosive 8701 and the slow detonation velocity explosive NQ. The experimental results show that the combination burster can efficiently control the FAE fuel dispersion and restrain the premature-combustion of the clouds, and the FAE clouds are basically strawhat shape and are reliably ignited. Thus it is feasible that the combination burster is used in the FAE bomb.
