Numerical Simulation and Experiment Investigation on Hypervelocity Jetting Projectile Charge Formation

In order to increase the effective quality of shaped charge jets,a new type of hypervelocity JPC was proposed by the study of internal explosion of jet collision region and the study of the formation mechanism of hypervelocity JPC,which could break through the high speed limitation of jets.The relationship between hypervelocity JPC and the structure parameters of the shaped charge was studied through numerous simulation and theoretical analysis,and furthermore an experiment was conducted.The penetration result shows good agreement with the simulation result and the theoretical analysis.The penetration ability of hypervelocity JPC has been improved greatly compared with EFP and classical shaped charge and there is no need to change the standoff and the diameter of shaped charge.
