为了克服爆炸物处理作业中塑料炸药填充聚能装药的不一致性，我们探索了使用敏化胶凝硝基甲烷液体作为若干聚能装药装置的填充物。穿透弹药外壳和引起爆燃的能力不仅取决于混合物的爆炸速度，如前几篇论文所研究的，而且还取决于所用装置的几何形状，在某些情况下还取决于装置中存在的限制。在这篇文章中，一系列的硝基甲烷为基础的炸药填充物，爆炸速度的范围内，被用来调查的性能，在目标穿透方面，圆锥形和碟形金属内衬和平底杯内衬安装在圆柱形管。当铜盘装置安装在金属管中时，获得了许多意想不到的结果，并证明了对靶的距离的穿透依赖性。通过对功能器械进行闪光X射线检查，证实了这些观察结果。对控制衬层性能的关键参数进行了讨论。
In an attempt to overcome the inconsistencies of plastic explosive–filled shape charges in EOD operations we have explored the use of sensitized gelled nitromethane liquid as a filling for a number of shaped charge devices. The ability to penetrate munition casings and induce deflagration is not only dependent on the velocity of detonation of the mixture, investigated in previous papers, but also on the geometry of the devices used and in some cases the confinement present in the device. In this article a range of nitromethane-based explosive fillings, with a range of velocities of detonation, was used to investigate the performance, in terms of target penetration, of both conical and dished metal liners and flat-bottomed cup liners mounted in cylindrical tubes. A number of unexpected results were obtained when copper dish devices were mounted in metal tubes and demonstrated a penetration dependence on standoff to the target. These observations were confirmed by flash X-ray investigation of the functioning devices. Some discussion of the critical parameters controlling the liner behavior has been undertaken.
