A computational fluid mechanics study of the detonation, collapse, jet formation, flight and properties of implosive shaped charge warhead systems. The study shows that a different liner collapse mechanism occurs from the familiar one of liner and conical shaped charge systems. The collapse was also seen to deviate from the ideal conditions initially envisioned. The resulting jet in some cases does not possess an inverse velocity gradient as in most classical cases. The jet in this case has distributions of mass, velocity, and energy along its length different from those of the classical cases. The different jet characteristics suggest a different type of target interaction than usual. Some of the novel features found numerically were confirmed experimentally. A comparative study of the properties of different types of shape charge warhead designs is also made.
