Abstract

Perforation devices including gas supply structures and methods of utilizing the same. The perforation devices include a magazine, a barrel, an action, and the gas supply structure. The magazine is configured to contain a plurality of cartridges. The barrel extends between a breech, which is configured to receive a selected cartridge of the plurality of cartridges that includes a selected projectile, and a muzzle, which is configured, upon firing of the selected cartridge, to permit the selected projectile to exit the barrel at a muzzle velocity and with a muzzle trajectory. The action is configured to transfer the selected cartridge from the magazine to the breech of the barrel and to fire the selected cartridge. The gas supply structure is configured to provide a gas stream to the barrel and includes a surface gas source and a gas supply conduit extending between the surface gas source and the barrel.

Claims (35)

1 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein an upper portion of the body has a generally conical configuration, a lower portion of the body has a truncated conical configuration, and a middle portion of the body bulges outward beyond the upper portion and the lower portion.

2 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein the crown configuration comprises a plurality of peaks spaced apart from each other and distributed circumferentially about the body, and the peaks are oriented toward a tip of the body.

3 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein the crown configuration comprises a plurality of slopes disposed circumferentially about the body.

4 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein the crown configuration comprises a plurality of valleys spaced apart from each other and circumferentially about the body.

5 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein the crown configuration comprises peaks which, in use:

create a circumferential alignment of the kinetic energy perforating round when perforating;

minimize an initial contact area between the kinetic energy perforating round and a target material; and/or

symmetrically distribute a force exerted by the kinetic energy perforating round about a circumference of the kinetic energy perforating round.

6 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein the crown configuration comprises slopes which, in use:

control a flow of target material displaced by the kinetic energy perforating round as it passes through a target; and/or

help to ensure symmetry in deformation of the target material through which the kinetic energy perforating round at least partially passes.

7 . A kinetic energy perforating round comprising:

a body defining an ignition housing entry port and ignition housing that are in communication with each other; and

a crown configuration disposed circumferentially about an outside diameter of the body,

wherein the crown configuration comprises a plurality of valleys which, in use:

displace target material as the kinetic energy perforating round passes into a target; and/or

reduce friction between the kinetic energy perforating round and material of the target.
