Investigations of the influence of the liner manufacturing precision on the penetration capability of shaped charge jets

The influence of the liner manufacturing precision or shaped charge jet characteristics and its penetration capability were investigated. Precise measurements of the liner thickness were performed and maximum deviations from the mean thickness were determined. The deviations are accepted as a meesure of the liner manufacturing precision. Shaped charges were prepared with liners varying in precision. Maximum values of the lateral jet velocity were determined on the basis of analysis of jet radiographs, and the correlation between them and the liner precision was examined. Depths of jets penetration into the monolithic steel targets were measured and compared with the results of the liner precision measurements. On this basis, some conclusions concerning the influence of the liner precision on the penetration capability of jets were drawn.
