Method for dispersing a jet from a shaped charge liner via spin compensated liners

摘要

A method is provided for dispersing and/or disrupting an aligned jet from a shaped charge round. A fluted shaped charge liner, typically used to compensate for spin effects on a coherent jet in a spin stabilized round is applied to a non-spinning round to produce a dispersed and/or disrupted jet pattern. The effect of disruption may also be altered by altering the subcalibration ratio (ratio of liner diameter to charge diameter). For a given liner diameter, an increase in charge diameter may result in increased dispersion of the jet. In addition, other types of spin compensated liners such as those using so-called metallurgical spin compensation, may be applied to a non-spinning round to produce dispersion and/or disruption of the jet. Moreover, the rate of spinning of the round (or the direction of spin) may be altered such that the spin compensated liner produces a dispersed jet pattern.
