Influence of Liner Form and Explosive on the Velocity and Mechanical Action of a Shaped-Charge Jet

The results of modeling the operation of shaped charges with conical, biconical, and elliptical liners and various detonation initiation schemes are presented. A comparison of the modeling results with data from experimental studies conducted on charge models and with the results of modeling by other authors has been carried out. A dependence of the leading part velocity of the copper shaped-charge jet for copper liners with apex angles of 44-50° on the parameter ρD2 in the low detonation velocity (D) and explosive density (ρ) range, is proposed.
