Claims31
Device for producing focused explosions and generating high speed fragments and a blastwave, the device comprising:
- a rigid outer shell;
- an explosive filling within said rigid outer shell, the explosive filling comprising a plurality of inwardly extending hollows, wherein said explosive filling is covered with an outer coating, said coating extending into said inwardly extending hollows;
- and
- a gap defined between the explosive filling and the rigid outer shell;
- and
- a hollow container for holding said explosive filling within said gap.

A method of manufacturing a device for focused explosions with controlled fragmentation, the method comprising:
- shaping an explosive charge with a plurality of hollows;
- lining the explosive charge;
- placing the explosive charge in a hollow container;
- placing the hollow container in a rigid shell;
- defining a gap between the container and the rigid shell, the gap extending between said hollow container and said rigid shell, the gap having a selected gap size, the gap size defining at least partly how an explosion at a given hollow impacts the rigid shell, thereby controlling fragmentation of said rigid shell.

Device for producing focused explosions, comprising:
- a rigid outer shell;
- a hollow container under said rigid outer shell;
- an explosive filling, the explosive filling placed within said hollow container, the explosive filling comprising a plurality of hollows, the hollows being lined with a coating, the coating comprising one member of the group consisting of copper and aluminum and alloys extending inwardly along respective axes towards an apex, the explosive filling being placed such that a gap is defined between said hollow container and said rigid outer shell, the gap extending under said rigid outer shell;
- and
- at least one detonation point within said explosive filling, each axis and corresponding apex being aligned with at least one said detonation point.
