Systems and methods for a firing pin

1. A disrupter cannon for launching a provided projectile in a forward direction toward an explosive device to disable or destroy the explosive device, the disrupter cannon comprising:

a barrel;

a breech cap coupled to the barrel; and

a firing assembly comprising a housing, a retainer, a magnet, a cover, and a firing pin, the housing is coupled to the breech cap; wherein:

the retainer, the magnet, the cover, and the firing pin are positioned in the housing, the firing pin is positioned between the cover and the breech cap;

the retainer has a bore therethrough;

the magnet has a bore therethrough, the magnet is positioned forward of the retainer such that the bore of the retainer and the bore of the magnet align;

the cover has a bore therethrough, the cover is positioned forward of the magnet such that the bore of the retainer and the bore of the magnet align with the bore of the cover;

the cover is positioned between the magnet and the firing pin such that the firing pin does not contact the magnet;

in a pre-firing position, the firing pin is proximate to the bore of the cover;

a first force provided by an expanding gas via the bore of the retainer, the bore of the magnet, and the bore of the cover moves the firing pin away from a pre-firing position to a firing position to launch the projectile;

as a magnitude of the first force decreases, a force of a magnetic field of the magnet moves the firing pin from the firing position to the pre-firing position.

2. The disrupter cannon of claim 1 wherein a magnitude of the first force acting on the firing pin overcomes a magnitude of the force of the magnetic field acting on the firing pin to move the firing pin from the pre-firing position to the firing position.

3. The disrupter cannon of claim 1 wherein after the first force moves the firing pin to the firing position, a magnitude of the first force decreases until it is less than a magnitude of the force of the magnetic field.

4. The disrupter cannon of claim 1 wherein the first force moves the firing pin with a momentum greater than a threshold for striking a provided cartridge to launch the projectile.

5. The disrupter cannon of claim 1 wherein as the first force moves the firing pin toward the firing position, a magnitude of the force of the magnetic field on the firing pin decreases.

6. The firing assembly of claim 1 wherein in the pre-firing position, the firing pin is in contact with the cover.

7. The firing assembly of claim 1 wherein in the pre-firing position, the firing pin covers the bore of the cover.

8. The firing assembly of claim 1 wherein the magnet has a donut-like shape.

9. The firing assembly of claim 1 wherein:

the retainer further comprises a protrusion;

the bore of the retainer is through the protrusion;

the protrusion is positioned in the bore of the magnet.

10. The firing assembly of claim 1 wherein the bores of the retainer, the magnet, and the cover align coaxially.

11. A firing assembly for launching a provided projectile, the firing assembly comprising:

a retainer having a bore therethrough;

a magnet having a bore therethrough, the magnet positioned proximate to the retainer such that the bore of the retainer and the bore of the magnet align;

a cover having a bore therethrough, the cover positioned over the magnet such that the bore of the retainer and the bore of the magnet align with the bore of the cover; and

a firing pin; wherein:

in a pre-firing position, the firing pin is proximate to the bore of the cover;

the cover is positioned between the magnet and the firing pin such that the firing pin does not contact the magnet;

a force of an expanding gas transmitted via the bore of the retainer, the bore of the magnet, and the bore of the cover moves the firing pin from the pre-firing position to a firing position to launch the projectile;

as a magnitude of the force of the expanding gas decreases, a force of a magnetic field of the magnet moves the firing pin from the firing position to the pre-firing position.

12. The firing assembly of claim 11 wherein in the pre-firing position, the firing pin is in contact with the cover.

13. The firing assembly of claim 11 wherein in the pre-firing position, the firing pin covers the bore of the cover.

14. The firing assembly of claim 11 wherein the magnet has a donut-like shape.

15. The firing assembly of claim 11 wherein:

the retainer further comprises a protrusion;

the bore of the retainer is through the protrusion;

the protrusion is positioned in the bore of the magnet.

16. The firing assembly of claim 11 wherein the bores of the retainer, the magnet, and the cover align coaxially.
