Abstract

A disruptor projectile includes a shaft made up of an elongate rod. A head piece assembly is connected to an end of the elongate rod. A post is located inside the head piece assembly. A tether line having an end with an eye splice attached around the post. The length of the tether line extends parallel to the elongate rod.

First claim

What is claimed is:

1. A disruptor projectile, comprising:
a shaft comprising an elongate rod;
a head piece assembly being connected to an end of the elongate rod;
an internal post being located inside the head piece assembly; and
a tether line having a first end comprising an eye splice around the internal post and having a length extending parallel to the elongate rod.

2. The disruptor projectile according to claim 1 , wherein the head piece assembly further comprises:
a solid body;
a circular cavity located within the solid body;
a cover; and
a channel,

wherein the tether line being at least partially disposed in the channel, and
wherein the internal post is located in the circular cavity.

3. The disruptor projectile according to claim 2 , wherein the cover includes an opening that fits over the internal post to hold the eye splice in the solid body, and
wherein the cover is at least partially embedded in the solid body at a front face of the solid body.

4. The disruptor projectile according to claim 2 , wherein the elongated rod is connected to the head piece assembly towards a side of the solid body.

5. The disruptor projectile according to claim 1 , wherein the shaft has a circular cross-section and a maximum diameter that is at most equal to a bore inner diameter of a disruptor.

6. The disruptor projectile according to claim 1 , wherein the tether line has a pull strength of at least 30,000 lbs.

7. A penetrator projectile for use in a disruptor, comprising:
a head piece assembly including a head distal end and a head proximal end;
a shaft including a shaft distal end and a shaft proximal end, wherein the shaft distal end is connected to the head proximal end; and
a tether line including a line distal end and a line proximal end,
wherein the line distal end is connected to the head piece assembly,
wherein the head piece assembly includes an internal post,
wherein the tether line includes an eye splice at the line distal end, and
wherein the eye splice surrounds the internal post.

8. The penetrator projectile according to claim 7 , wherein the head piece assembly further comprises:
a solid body;
a circular cavity located within the solid body;
a cover disposed over the solid body, and
a channel, the tether line being at least partially disposed in the channel, and
wherein the internal post is located in the circular cavity.

9. The penetrator projectile according to claim 8 , wherein the cover includes an opening that fits over the internal post to hold the eye splice in the solid body, and
wherein the cover is at least partially embedded in the solid body at a front face of the solid body.

10. The penetrator projectile according to claim 8 , wherein the shaft distal end is connected to the head proximal end towards a side of the solid body.

11. The penetrator projectile according to claim 7 , wherein the shaft has a circular cross-section and a maximum diameter that is at most equal to a bore inner diameter of a disruptor.

12. The penetrator projectile according to claim 8 , wherein the tether line has a pull strength of at least 30,000 lbs.

13. An apparatus, comprising:
an EOD disruptor having a barrel;
a blank cartridge being loaded in the EOD disruptor; and
a muzzle-loaded projectile being disposed in front of the blank cartridge,
wherein the muzzle-loaded projectile includes a shaft portion at least partially disposed in the barrel and a head portion disposed outside of the barrel,
wherein the head portion includes an internal post, and
wherein a tether line is attached to the internal post.

14. The apparatus according to claim 13 , wherein the head portion of the muzzle-loaded projectile further comprises:
a solid body;
a circular cavity located within the solid body;
a cover disposed over the solid body; and
a channel, the tether line being at least partially disposed in the channel, and
wherein the internal post is located in the circular cavity.

15. The apparatus according to claim 14 , wherein the cover includes an opening that fits over the internal post to hold the tether line in the solid body, and
wherein the cover is at least partially embedded in the solid body at a front face of the solid body.

16. The apparatus according to claim 14 , wherein the shaft is connected to the head portion towards a side of the solid body.

17. The apparatus according to claim 14 , wherein the solid body includes a width dimension, a length dimension, and a depth dimension, and
wherein the depth dimension is equal to a diameter of the shaft portion.

18. The apparatus according to claim 13 , wherein the shaft portion has a circular cross-section and a maximum diameter that is at most equal to a bore inner diameter of the barrel.

19. The apparatus according to claim 13 , wherein the tether line has a pull strength of at least 30,000 lbs.

20. The apparatus according to claim 13 , wherein the tether line further comprises an eye splice at an end of the tether line, and wherein the eye splice is oriented around the internal post.

21. The apparatus according to claim 13 , wherein the blank cartridge comprises a 12-gauge cartridge.
