Apparatus for dispersing a jet from a shaped charge liner via non-uniform liner mass

摘要

The jet of a shaped charge ammunition round may be disrupted and dispersed by altering the local charge to mass ratio within the shaped charge round. A shaped charge round typically produces a coherent jet suitable for penetrating thick armor or the like. However, such coherent jets may be unsuitable for damaging thinner targets. By placing a mass (or removing a mass) at a local portion of the shaped charge liner, the outer casing, or the explosive charge, the local charge to mass ratio may be altered, causing disruption of the coherent jet. A wire, wrapped around the charge liner in a spiral fashion, may be used to produce a substantially helical or spiral shaped jet which may be particularly applicable for damaging missiles or the like.
