射孔弹用RDX基含铝炸药性能实验及分析

针对传统的常温射孔弹用R852炸药,提出了RDX基含铝高威力炸药作为射孔弹用炸药。通过理论计算、RDX基含铝炸药的机械感度、静电火花感度、5 s延滞期爆发点测试以及装填射孔弹后的地面模拟装枪穿目标靶试验,得出RDX含铝炸药作为射孔弹用炸药的可行性和优势。结果显示RDX基含铝炸药具有合适的机械感度,耐热性和压制性良好,适用于射孔弹用装药;与装填R852炸药的射孔弹穿深性能相比,装填RDX基含铝炸药射孔弹的地面模拟装枪侵彻柱状混凝土靶穿深降低了7.5%,但装填RDX基含铝炸药射孔弹在柱状混凝土靶上形成干净的射流孔道、孔道无明显白色压实带,在射流孔道及孔道末端出现密集型微裂缝。

Performances Experiments and Analysis of RDX-based Aluminized Explosives for Perforating Charge

Based on R852, a traditional explosive for perforating charge at room temperature, a RDX-based powerful aluminized explosive is proposed as the explosive for perforating charge. Through theoretical calculation of mechanical sensitivity and electrostatic spark sensitivity, 5 senconds delay bursting point test and ground target penetrated test, the RDX-based aluminized explosive is feasible and advantageous as the explosive for perforating charge. The RDX-based aluminized explosive has suitable mechanical sensitivity, good heat resistance and compactibility, and is suitable for perforating charge. Ground simulation experiments found that the charge with RDX-based aluminized explosive penetrated a cylindrical concrete target shallower than the charge with R852 explosive by 7.5%, however, the channel induced by the charge with RDX-based aluminized explosive is clean and without obvious white compacted zones, and dense micro-fractures appeared on the wall and the end of the channel.
