分散药T型装药控制二次引爆型FAE云雾研究

Study on Control Cloud of Twice-Detonating FAE by T-Type Charge of Burster

为了控制新型FAE弹体云雾的窜火、形状、直径与高度等,设计出直径不同的两种药柱间隔装填的分散药T型装药结构,着重对两种药柱的半径、高度、爆速、密度、分散药燃料比进行了设计。在假设小药柱以平面爆轰波引爆大药柱的前提下,对大药柱爆轰波正常传播条件进行了理论推导。选择宏观固态燃料,对Φ330mm×430mm的新型FAE炸弹进行静爆实验;运用柯达高速运动系统观测云雾形成及爆轰过程,并对FAE云雾的直径、高度和体积进行了处理和分析。结果表明,分散药T型装药能有效地控制FAE云雾的形状、直径、高度以及云雾体积,特别是对遏制云雾窜火有很好的效果。

To control the premature-combustion, shape, diameter and height of the FAE clouds under the new FAE bomb, T-type charge with different diameters made of the two kinds of explosive is designed. The two kinds of explosive are charged in interval and there is the inert material in the remainder space between them. The designed and chosen factors of the radius, height, detonating velocity, density and the ratio of burster and fuel are given on the two kinds of explosive in accordance with its aim and function. The propagating condition of the big eharge＇s detonating wave is theoretically derived in the precondition of the big charge is ignited by the planar detonating wave of the small charge. The static detonation test is carried out bya new bomb of Φ330mm×430mm with the macroscopical solid fuel. The processes that the fuel dispersed and the FAE clouds detonated are recorded by a KODAK EKTAPRO EM motion analyzer. The diameter, height and volume of the FAE clouds are analyzed. The results demonstrate that T-type charge of burster controls the shape, diameter, height and the volume of the FAE clouds efficaciously, and restrains the premature-combustion specially.
