Energetics train reaction and method of making an intensive munitions detonator
A detonator formed entirely from a plurality of discrete segments of an insensitive energetic composition, each of the segments employed in the detonator being compacted at different pressures from powder and/or granules of insensitive energetic composition so as to form an energetic train which sequences detonation of the individual segments. Initiation of a main charge can only be effected when a last segment in the detonation train is initiated. Detonation starts with a first segment in the detonation train which is produced under the lowest compaction pressure, and then detonation progresses to a last segment compacted under a higher compaction pressure. The first segment can be detonated by a safety fuse or detonating cord, and the last segment can only be detonated by the next to the last segment in the detonation train.
1. A detonator for a pyrotechnic device consisting of a plurality of discrete segments of a single insensitive energetic composition, said plurality of discrete segments comprising at least a first, second and third discrete segment, wherein the plurality of segments are each compacted under different pressures from powder and/or granules of insensitive energetic composition so as to form an energetic train which sequences detonation of the individual segments starting with the first segment produced under the lowest compaction pressure and then progressing to the subsequent segments compacted under higher compaction pressures, wherein the first segment can only be ignited by a pyrotechnic fuse or detonation cord, and each subsequent segment can only be ignited by the segment immediately preceding it in the energetic train, and wherein the pyrotechnic device can only be ignited by the last segment.
2. The detonator of claim 1 , wherein said detonator is formed from granules and/or powdered RDX.
3. The detonator of claim 2 , wherein the first segment of RDX is compacted under a pressure of about 2,000 psi, and the last segment of RDX is compacted under a pressure of about 4,000 psi.
4. The detonator of claim 1 , wherein said detonator is formed from granules and/or powdered HMX.
5. The detonator of claim 1 , wherein the pyrotechnic device is selected from the group consisting of hand grenades, bombs, rockets, mortars, mines, satchel charges, bazooka shells, artillery shells, destructor assemblies, and ammunition.
