This results in its small part of jet being projected at a lower velocity than jet formed later behind it. Articles needing additional references from October All articles needing additional references All articles with unsourced statements Articles with unsourced statements from October The dispersion of the second phase can be achieved also with castable alloys e. A description of Munroe's first shaped-charge experiment appears on p. When the shaped charge detonates, most of its energy is focused on the steel plate, driving it forward and pushing the test gas ahead of it. The dispersion of the second phase can be achieved also with castable alloys e.
By , Shardin believed that hollow-charge effects were due to the interactions of shock waves. The penetration depth is proportional to the maximum length of the jet, which is a product of the jet tip velocity and time to particulation. If the hollow is properly shaped usually conically , the enormous pressure generated by the detonation of the explosive drives the liner in the hollow cavity inward to collapse upon its central axis. Tactical Missile Warheads , Joseph Carleone ed. The newer rod projectiles may be effective against the more heavily armored areas of MBTs. Among the experiments made
Shaped Charge/Hypervelocity Penetration
The key to the effectiveness of the hollow charge is its diameter. This page was last edited on 31 March , at Fundamentals of Shaped Charges. At typical velocities, the penetration process generates such enormous pressures that it may be considered hydrodynamic ; to a good approximation, the jet and armor may be treated as inviscid , incompressible fluids see, for example,  , with their material strengths ignored.
Description: The lining is surrounded with explosive, the explosive then encased within a suitable material that serves to protect the explosive and to confine tamp it on detonation. In a Russian scientist proposed that a shaped charge originally developed for piercing thick steel armor be adapted to the task of accelerating shock waves.
