Abstract

A ballistic transfer system, comprising: a housing, wherein the housing is cylindrical, wherein the housing comprises: a central bore that traverses a length of the housing; a first end; wherein the first end is disposed about a first ballistic apparatus; and a second end, wherein the second end is opposite to the first end, wherein the second end is disposed about a second ballistic apparatus; an alignment insert, wherein the alignment insert is secured into the housing; a first detonation transfer line, wherein a portion of the first detonation transfer line is disposed within the alignment insert; and a second detonation transfer line, wherein a portion of the second detonation transfer line is disposed within the alignment insert.

First claim

What is claimed is:

1. A ballistic transfer system, comprising:
a housing, wherein the housing is cylindrical, wherein the housing comprises:
a central bore that traverses a length of the housing;
a first end; wherein the first end is disposed about a first ballistic apparatus; and
a second end, wherein the second end is opposite to the first end, wherein the second end is disposed about a second ballistic apparatus;

an alignment insert, wherein the alignment insert is secured into the housing;
a first detonation transfer line, wherein a portion of the first detonation transfer line is disposed within the alignment insert; and
a second detonation transfer line, wherein a portion of the second detonation transfer line is disposed within the alignment insert.

2. The ballistic transfer system of claim 1 , wherein the housing further comprises an internal cavity, wherein the alignment insert is disposed into the internal cavity, wherein a central axis of the alignment insert is aligned with the central bore of the housing.

3. The ballistic transfer system of claim 1 , wherein the alignment insert comprises a material selected from a group consisting of aluminum, steel, glass-filled Nylon, and combinations thereof.

4. The ballistic transfer system of claim 1 , wherein the first detonation transfer line comprises a material selected from a group consisting of octogen, hexanitrostilbene, 2,6-bis(picrylamino)-3,5-dinitropyridine, 4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo [5.5.0.05,9.03,11]-dodecane, triaminotrinitrobenzene or 2,4,6-triamino-1,3,5-trinitrobenzene, nonanitroterphenyl, hexogen, pentaerythritol tetranitrate, 1,3,5-trinitro-2,4,6-tripicrylbenzene, 1,3-diamino,2,4,6-trinitrobenzene, hexanitrobenzene, nitrotriazolone, and combinations thereof.

5. The ballistic transfer system of claim 1 , wherein the second detonation transfer line comprises a material selected from a group consisting of octogen, hexanitrostilbene, 2,6-bis(picrylamino)-3,5-dinitropyridine, 4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo [5.5.0.05,9.03,11]-dodecane, triaminotrinitrobenzene or 2,4,6-triamino-1,3,5-trinitrobenzene, nonanitroterphenyl, hexogen, pentaerythritol tetranitrate, 1,3,5-trinitro-2,4,6-tripicrylbenzene, 1,3-diamino,2,4,6-trinitrobenzene, hexanitrobenzene, nitrotriazolone, and combinations thereof.

6. The ballistic transfer system of claim 1 , wherein the portion of the first detonation transfer line is parallel to the portion of the second detonation transfer line within the alignment insert.

7. The ballistic transfer system of claim 1 , wherein the portion of the first detonation transfer line is in a spiral around the portion of the second detonation transfer line within the alignment insert.

8. The ballistic transfer system of claim 1 , wherein the portion of the first detonation transfer line is looped back and forth parallel to the central bore of the housing within the alignment insert, wherein the portion of the second detonation transfer line is disposed in a straight line parallel to the central bore of the housing within the alignment insert.

9. The ballistic transfer system of claim 1 , wherein the alignment insert comprises additional pieces of detonating cord disposed along the portion of the first detonation transfer line or the portion of the second detonation transfer line.

10. The ballistic transfer system of claim 1 , further comprising a second alignment insert, wherein the second alignment insert abuts alignment insert.

11. The ballistic transfer system of claim 1 , wherein the first detonation transfer line or the second detonation transfer line comprises a jacket, wherein the jacket is configured to act as a flyer plate in order to increase pressure transferred between the first detonation transfer line and the second detonation transfer line during a transfer of detonation.

12. The ballistic transfer system of claim 1 , wherein the alignment insert comprises a channel between the portion of the first detonation transfer line and the portion of the second detonation transfer line.

13. A ballistic transfer system, comprising:
a first ballistic apparatus, wherein the first ballistic apparatus comprises a first detonation transfer line;
a second ballistic apparatus, wherein the second ballistic apparatus comprises a second detonation transfer line; and
an alignment insert, wherein the alignment insert is disposed between the first ballistic apparatus and the second ballistic apparatus, wherein a portion of the first detonation transfer line is disposed within the alignment insert, wherein a portion of the second detonation transfer line is disposed within the alignment insert.

14. The ballistic transfer system of claim 13 , further comprising a housing, wherein the alignment insert is disposed at a first end of the housing, wherein the housing is disposed internally between the first ballistic apparatus and the second ballistic apparatus.

15. The ballistic transfer system of claim 13 , wherein the portion of the first detonation transfer line is parallel to the portion of the second detonation transfer line within the alignment insert.

16. The ballistic transfer system of claim 13 , wherein the portion of the first detonation transfer line is in a spiral around the portion of the second detonation transfer line within the alignment insert.

17. The ballistic transfer system of claim 13 , wherein the portion of the first detonation transfer line is looped back and forth parallel to a central bore of a housing within the alignment insert, wherein the portion of the second detonation transfer line is disposed in a straight line parallel to the central bore of the housing within the alignment insert.

18. The ballistic transfer system of claim 13 , wherein the alignment insert comprises additional pieces of detonating cord disposed along the portion of the first detonation transfer line or the portion of the second detonation transfer line.

19. The ballistic transfer system of claim 13 , wherein the first detonation transfer line or the second detonation transfer line comprises a jacket, wherein the jacket is configured to act as a flyer plate in order to increase pressure transferred between the first detonation transfer line and the second detonation transfer line during a transfer of detonation.

20. The ballistic transfer system of claim 13 , wherein the first ballistic apparatus is coupled to the second ballistic apparatus through a pin and box connection.
