Magnetic screening against shaped-charge action

Abstract

The present paper considers the possibility of using magnetic fields for the antiterrorist protection of various objects against shaped-charge action by means of their magnetic screening — the creation of a magnetic field in the space ahead of the object being protected from attack. The results of an experimental and numerical investigation of the effect of the magnetic field generated in a shaped-charge liner on the structure of the shaped charge jets and penetration into a target are presented. It is shown that a considerable decrease in the depth of penetration of shaped- charge jets into the target can be achieved at moderate magnetic fields of a few tenths of a tesla.
