A device for the controlled initiation of a subdetonative reaction of an explosive charge arranged in a shell includes at least one explosive charge core extending in a region of a longitudinal axis of the explosive charge. A transverse dimension of the explosive charge core is adaptable to a radial extent of the shell in a longitudinal direction of the explosive charge, while a charging of the explosive charge core is set homogeneously or locally variably over a length of the explosive charge core with respect to a type of explosive material.

1. A device for the controlled initiation of a subdetonative reaction of an explosive charge arranged in a shell, the device comprising: at least one explosive charge core extending along a longitudinal axis of the explosive charge, the explosive charge core including: a transverse dimension that varies according to a radius of the shell along the longitudinal axis, anda length over which a charging of explosive material of the explosive core is locally varied with respect to a type of the explosive material. 2. The device according to claim 1, wherein the charging of the explosive charge core varies according to the shell radius along the longitudinal axis. 3. The device according to claim 1, wherein the explosive material is arranged in the explosive charge core based on density and/or percentage composition of the explosive material. 4. The device according to claim 3, wherein a mixture of explosive molecules and inert binders comprise the explosive charge core, and wherein the inert binders comprise at least one of HTBP, silicone rubber, polyurethane rubber, polystyrene, Estane, nylon, wax and graphite. 5. The device according to claim 3, wherein a detonation speed of the explosive charge core is equal to or slightly less than a detonation speed of the explosive charge. 6. The device according to claim 3, wherein a self-ignition temperature of the explosive charge core is below 230° C. 7. The device according to claim 1, wherein a ratio of the transverse dimension of the explosive charge core to a diameter of the explosive charge is between 1/10 and 1/30. 8. The device according to claim 1, wherein the explosive charge core is surrounded by a sheath. 9. The device according to claim 8, wherein a wall thickness and/or a material of the sheath varies according to the radius of the shell along the longitudinal direction of the explosive charge. 10. The device according to claim 8, wherein a wall thickness of the sheath lies in a range of sizes of the transverse dimension of the explosive charge core, which is less than said wall thickness. 11. The device according to claim 1, wherein the explosive charge core is surrounded by a tube. 12. The device according to claim 11, wherein a wall thickness and/or a material of the tube varies according to the radius of the shell along the longitudinal direction of the explosive charge. 13. The device according to claim 11, wherein a wall thickness of the tube lies in a range of sizes of the transverse dimension of the explosive charge core, which is less than said wall thickness. 14. The device according to claim 1, wherein the explosive charge comprises a casted explosive charge with a CHNO-based explosive molecule comprised of at least one of RDX, HMX, NTO, FOX-7 and FOX-12, encapsulated in an inert binder comprised of at least one of HTPB, silicone rubber, polyurethane rubber, polystyrene, Estane and nylon. 15. The device according to claim 14, wherein the casted explosive charge further comprises additional metal powder comprising one or more of aluminum, magnesium, zirconium, titanium, tungsten, titanium carbide, zirconium carbide and ammonium perchlorate (AP). 16. The device according to claim 1, wherein the explosive charge is surrounded by a shell made from at least one of metals, plastics or composite materials. 17. The device according to claim 16, wherein the metal is at least one of steel, aluminum, titanium and corresponding alloys thereof, and wherein the composite materials are at least one of GRP, CFRP, CRC and CFRC. 18. The device according to claim 16, wherein a ratio of a mass of the shell to a mass of the explosive charge is between 1.0 and 8.0, and wherein a static failure pressure of the shell is under 6 kbar.
