Abstract

Abstract

A hemispherical liner was designed and the cushion with the same curvature as the liner was placed between the liner and the explosive.And the forming process of an explosively -formed penetrator from the liner made by reactive material was recorded by using a high -speed camera.Experimental results show that the liner made by reactive materials can be forged into an energetic penetrator under explosive loading and the velocity of the energetic penetrator can be up to about 2km/s.After perforating the armor steel target with the thickness of 20mm, the energetic penetrator reacts acutely and produces a great deal of gas.The penetrating process of the energetic penetrator is maintained by kinetic energy and chemical reaction.Ablation can obviously be observed during perforation.The diameter of perforation is about 0.5times as large as the diameter of charge and the penetrating depth is about 1.1times as large as the diameter of charge.
