  • For special requirements of penetrating multi-layer steel target, a design of explosively formed projectile (EFP) and its experimental study have been carried out.A compressed EFP assembly with a 60 mm diameter of liner has been designed using the curved variable thickness liner design.The shape and velocity of the EFP when penetrating through the multi-layer steel target were measured with X-ray photography.According to the experimental results, the EFP shows the characteristics of moderate speed, good compactness and small length-radius ratio.In the process of penetrating multi-layer steel target, the EFP has stable performance, and smash phenomenon does not exist.The experimental results show that it can penetrate through the six-layer steel target with thickness of 6 mm and spacing of 2 m.
