Abstract

A gun firing method for multiple projectiles to be fired simultaneously in a predetermined symmetrical pattern, whereby some of the multiple projectiles are modified by moving the center of mass of the projectile away from it'"'"'s central axis. This in combination with bring fired from a rifled gun barrel will impart velocity to the projectile upon exiting the gun barrel at right angles to the barrel. This velocity along with the higher muzzle velocity will cause the modified projectile to diverge away from the trajectory of a standard projectile. The magnitude of the divergence will vary with the distance the projectile'"'"'s center of mass is away from it'"'"'s central axis, and the placement of the modified projectile strikes around the bull'"'"'s-eye will be determined by the loading orientation of the multiple projectiles in the chamber of the gun. Simultaneously firing a multiplicity of standard and modified projectiles will produce a symmetrical dispersion pattern on a target, which substantially increases the hit probability of the gun.

Claims

1. A system for projectile dispersion to improve the hit probability on a target comprising:

a plurality of projectiles each having a main body, having a front end a back end and a side;

wherein each said projectile has a central axis located longitudinally from said back end to said front end of said projectile in the center of said projectile;

wherein at least one projectile of said plurality of projectiles have centers of mass which are offset some distance from said central axis of said projectiles;

a gun having a rifled barrel;

wherein there is a means to orient said offset center of mass of each said projectile radially in relation to said central longitudinal axis of each said projectile prior to firing whereby a predetermined pattern is created when at least one of said projectiles of said plurality of projectiles are fired simultaneously by said gun on a target.

2. The system of claim 1 wherein,

said offset centers of mass of each said projectile are located at substantially the same distance from said central longitudinal axis.

3. The system of claim 1 wherein,

said offset centers of mass of each projectile are located at substantially different distances from said central longitudinal axis.

4. The system of claim 2. wherein,

said simultaneously fired projectiles consists of one said standard projectile followed by said projectiles with said differing offset centers of mass with differing vectors of orientation.

5. The system of claim 4. wherein,

said means to orient each projectile of said projectiles with offset centers of mass is arranged to provide orientation of said projectiles with offset centers of mass whereby the predetermined pattern created is substantially linear and horizontal.

6. The system of claim 2. wherein,

said means to orient each projectile of said projectiles with offset centers of mass is arranged to provide orientation of said projectiles having said offset centers of mass radially at substantially different vectors.

7. The system of claim 6. wherein,

said means to orient each projectile of said projectiles with offset centers of mass is arranged to provide orientation of successive projectiles having said offset centers of mass radially approx. 90 degrees from the previous said projectile having said offset center of mass.

8. The system of claim 7. wherein,

said gun is arranged to fire simultaneously four of said projectiles with said offset centers of mass with said approx. 90 degree differing vectors of orientation whereby the predetermined pattern created is substantially shaped as a diamond around the aim point from said gun.

9. The system of claim 7. further comprising,

at least one standard projectile with a center of mass along its said central axis interspersed among said projectiles whose offset centers of mass have said approx. 90 degree differing vectors of orientation.

10. The system of claim 9. wherein,

said simultaneous firing consists of one standard projectile and four of said projectiles with said offset centers of mass with said approx. 90 degree differing vectors of orientation whereby the predetermined pattern created is substantially shaped as a diamond around a central hit point from said standard projectile.

11. The system of claim 1 further comprising,

a means of indicating said radial orientation of said projectiles with said offset centers of mass.

22. The system of claim 1 further comprising,

a means to offset said centers of mass of said projectiles selected from the group consisting of extraction of mass from said side of said projectile, attachment of mass to said side of said projectile, replacement of portions of said body of said projectile with a less dense material than the material comprising the projectile, replacement of portions of said body of said projectile with a more dense material than the material comprising the projectile, replacement of certain portions of said body of said projectile with said less dense material and simultaneous replacement of other portions of said body with a more dense material, and formation of at least one void within said body of said projectile.

12. A method for projectile dispersion to improve hit probability on a target comprising:

shifting the center of mass a distance away from the central longitudinal axis of at least one of a plurality of projectiles;

firing said projectiles simultaneously from a gun having a rifled barrel;

orienting said offset center of mass radially in relation to said central longitudinal axis of each said projectile prior to firing said plurality of projectiles from said gun whereby a predetermined pattern is created when at least one of said projectiles of said plurality of projectiles are fired simultaneously by said gun on a target.

13. A method as recited in claim 12. wherein,

shifting the offset centers of mass of each said projectile involves locating the offset centers of mass at substantially the same distance from said central longitudinal axis.

14. A method as recited in claim 12. wherein,

shifting the offset centers of mass of each said projectile involves locating the offset centers of mass at substantially different distances from said central longitudinal axis.

15. A method as recited in claim 13. wherein,

simultaneous firing includes one said standard projectile and said projectiles with said differing offset centers of mass with said differing vectors of orientation.

16. A method as recited in claim 15. wherein,

orienting said projectiles with said differing offset centers of mass with said different vectors of orientation is performed whereby a predetermined pattern is created that is substantially linear and horizontal.

17. A method as recited in claim 12. wherein,

orienting said projectiles with said offset centers of mass radially at substantially different vectors.

18. The method as recited in claim 17. wherein,

orienting each successive projectile of said projectiles having said offset centers of mass radially at a vector which is approx. 90 degrees from the previous projectile having said offset center of mass.

19. The method as recited in claim 18. wherein,

firing said projectiles from said gun is performed simultaneously with four of said projectiles with said offset centers of mass with said approx. 90 degree differing vectors of orientation whereby the predetermined pattern created is substantially shaped as a diamond around the aim point from said gun.

20. The method as recited in claim 18. wherein,

23. The method as recited in claim 12 wherein

shifting the center of mass off the central longitudinal axis of each projectile is performed by a step selected from the group consisting of extracting a portion of mass from said side of said projectile, adding mass to said side of said projectile, replacing portions of said body of said projectile with a less dense material than the material comprising the projectile, replacing portions of the body of said projectile with a more dense material than the material comprising the projectile, replacing certain portions of said body of said projectile with a less dense material than the material comprising the projectile while simultaneously replacing other portions of the body of said projectile with a more dense material than the material comprising the projectile, and forming at least 1 void within the body of said projectile between said side and said central longitudinal axis
