Discussions to Shaped Charge Jet Tests after MIL-STD-2105B
Abstract
In contrast to the fragment impact test the shaped charge jet impact test No. 5.2.6 of MIL STD 2105 B is very conservative. The detailed description for the shaped charges, which should be used, is already modified from the first edition of the MIL STD 2105 B. The 50 mm Rockeye warhead, fired at 147 mm stand-off, is not internationally available to everybody and represents not the real threat by modern shaped charge systems. On one hand it exist a very large number of shoulder launched projectiles with about 300 mm to 400 mm perforation capabilities. But the missile warheads have mostly 100 mm to 150 mm diameters with perforation potentials of 800 mm to 1.200 mm and jet tip velocities over 9 mm/microseconds. After the perforation of 100 mm RHA or less the residual jet tip velocities are over 8 mm/microseconds with large jet diameters. Further missile WH are nearly 100% using now tandem shaped charges, where the jet of the precursor charge can sensitise propellant and high explosive charges, where the later arriving main jets can start now violent reactions. The initiation criteria for shaped charge jets as function of jet velocities, diameter, material, acceptor charge configurations, covered or not, unconfined and confined etc. will be shortly described. Finally it will be tried to give recommendations for different levels of shaped charge threats.
