Abstract

Charged projectile assemblies include a housing and an electronic assembly configured to produce an electric field about at least a portion of the housing of the projectile. Cartridge assemblies for use with firearms include charged projectiles. Methods of charging a projectile include forming an electric field about at least a portion of a projectile and extending the electric field at least partially between a forward portion of the projectile and an aft portion of the projectile.

Claims (39)

1. A charged projectile assembly comprising:

a projectile comprising a housing; and an electronic assembly comprising:

a first electrically conductive region proximate a forward portion of the projectile;

a second electrically conductive region proximate an aft portion of the projectile; and

an electrical power source electrically coupled to at least one of the first electrically conductive region or the second electrically conductive region, wherein electronic assembly is configured to discharge the electrical power source through the at least one of the first electrically conductive region or the second electrically conductive region to produce an electric field about at least a portion of the housing of the projectile extending between the first electrically conductive region and the second electrically conductive region.

2. The charged projectile assembly of claim 1 , wherein the first electrically conductive region proximate the forward portion of the projectile and the second electrically conductive region proximate the aft portion of the projectile are both electrically coupled to the electrical power source.

3. The charged projectile assembly of claim 2 , wherein the electrical power source of the electronic assembly comprises a capacitor positioned within the housing of the projectile, wherein the capacitor is selectively electrically connectable to the first conductive region and the second conductive region to produce the electric field.

4. The charged projectile assembly of claim 3 , wherein the electronic assembly is configured to apply potentials of opposite polarity to the first conductive region and the second conductive region in order to produce the electric field extending between the first conductive region and the second conductive region.

5. The charged projectile assembly of claim 4 , wherein at least one of the first conductive region or the second conductive region comprises a dielectric coating on at least an exterior portion thereof.

6. The charged projectile assembly of claim 1 , wherein the electronic assembly further comprises a time delay configured to delay an electronic discharge of the electronic assembly to produce the electric field.

7. The charged projectile assembly of claim 6 , wherein the time delay comprises a pyrotechnic time delay.

8. The charged projectile assembly of claim 7 , wherein the charged projectile assembly further comprises a case having a reactive material disposed therein for imparting an initial velocity to the housing of the projectile.

9. The charged projectile assembly of claim 8 , wherein the pyrotechnic time delay is configured and located to be initiated by the reactive material within the case.

10. The charged projectile assembly of claim 1 , wherein the charged projectile assembly comprises a cartridge for use with a sniper rifle.

11. A cartridge assembly for use with a firearm, the cartridge comprising:

a case having a reactive material disposed therein; and

a charged projectile disposed at least partially within the case, the charged projectile comprising:

a housing; and

an electronic assembly comprising:

a first electrically conductive region;

a second electrically conductive region; and

an electrical power source electrically coupled to at least the first electrically conductive region, the electronic assembly configured to produce an electric field about at least a portion of the housing of the projectile between the first electrically conductive region and the second electrically conductive region during flight of the charged projectile and before the charged projectile reaches an intended target.

12. The cartridge assembly of claim 11 , wherein the cartridge assembly comprises a cartridge assembly for use with a sniper rifle.

13. The cartridge assembly of claim 11 , wherein the electronic assembly is configured to produce the electric field after being separated from the case by the reactive material.

14. A cartridge assembly for use with a firearm, the cartridge comprising:

a case having a reactive material disposed therein; and

a charged projectile disposed at least partially within the case, the charged projectile comprising:

a housing; and

an electronic assembly configured to produce an electric field about at least a portion of the housing of the projectile, the electronic assembly comprising:

at least one electrically conductive region; and

an electrical power source electrically coupled to the at least one electrically conductive region, wherein the electronic assembly is configured to initiate production of the electric field by the reactive material within the case.

15. A method of charging a projectile, the method comprising:

forming an electric field about at least a portion of the housing of the projectile of claim 1 with the electronic assembly; and

extending the electric field at least partially between a forward portion of the projectile and an aft portion of the projectile.

16. The method of claim 15 , further comprising launching the projectile.

17. The method of claim 16 , further comprising initiating the electric field after the projectile is launched.

18. The method of claim 16 , further comprising initiating the electric field before or during the launching of the projectile.

19. The method of claim 15 , wherein forming an electric field about at least a portion of a projectile comprises discharging a capacitor within the projectile.

20. The method of claim 19 , further comprising delaying the discharge of the capacitor within the projectile with a time delay device.
