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. |
