Shaped Charge Jet Flash Radiograph Digitization

Abstract : The flash radiograph digitization of shaped charge jets provides warhead designers with the data required for empirically based models, as well as the jet characterization used for comparison with high rate continuum modeling. Reduced digitization results include jet tip velocity, jet accumulated length, accumulated mass, accumulated energy, break up time, maximum and average jet diameters, and the ductility factor (0). This Computer program provides a systematic method of characterizing a shaped charge warhead by means of quantifying the shaped charge jet parameters. The break up time, for instance, shows when the shaped charge jet particulates. This parameter is essential for shaped charge performance, because it relates to how deep the penetration is, since the penetration is decreased significantly once the jet particulates. The Q ductility factor is another example of the characterization of the jet. In general, the higher the number Q (more ductile), more penetration is expected. The accumulated mass and break up time from the digitization computations can be used in penetration simulation prediction.
