含能射孔弹双层药型罩穿孔性能研究

含能射孔弹药型罩主要采用含能材料压制的单金属药型罩,该弹穿深性能低。而双层含能射孔弹内层采用高钨配方,外层采用含能材料,既提高了穿深性能,又清洁了孔道。本文中,设计了一种新结构的压罩模具,成功压制了双层药型罩,打靶结果为双层药型罩射孔弹的穿深为695 mm,单金属药型罩为400 mm,双层药型罩的穿深比单金属药型罩提高73.8%,表明与单金属含能射孔弹相比,双层含能射孔弹有明显的优势。

Study on Penetration Performance of Bi-layer Liner in Energetic Penetrating Charge

Metal liner of energetic penetrating charge,which has a single layer,is usually made of energetic materials.Its penetration depth is low.While the bi-layer energetic penetrating charge with energetic materials outside and high quality tungsten inside not only increases the depth,but also has a self-cleaning function.A shaped charge liner mold with a new structure was designed,which successfully fabricated bi-layer self-cleaning shaped charge liner.Concrete target test shows that the bi-layer self-cleaning perforating charge has a 695 mm penetration depth,increased by 73.8％ compared with the single layer self-cleaning shaped charge having a 400 mm perforating depth.These results indicate that the bi-layer selfcleaning shaped charge has a greater advantage in perforating depth.
