Abstract:
1. An explosive structure of the fragmentation type, comprising: an outer casing comprising an energy dense explosive material and having an inner surface defining a chamber; means for propagating shock waves across the inner surface from a selected one of at least first and second detonation points within the casing; first means for directing shock waves, propagated from the first detonation point, against at least a selected portion of the inner surface in a first pattern for scoring and weakening the casing along first, segment-defining lines; second means for directing shock waves, propagated from the second detonation point, against the selected portion of the inner surface in a second pattern for scoring and weakening the casing along second, segment-defining lines, the segments of the second pattern being larger than the segments of the first pattern; and means for fragmenting the casing along the resulting, segment-defining lines scored in the casing.
