Abstract

It is proposed to combine the cascade effect of frangible pellets with sub-projectiles made of ductile heavy metal, that is, to produce a munition in which the advantages of for example frangible pellets of a central penetrator are combined with the advantages of the ductile heavy metal in an external penetrator\whereby an improved performance on various targets is achieved along with deeper impact speeds.

Claims (32)

1. A universal KE-projectile comprising:

a projectile tip;

a projectile sleeve;

a projectile tail end including a central penetrator assembled from frangible pellets;

an exterior penetrator having a curved or banana shape, the exterior penetrator being connected around the central penetrator and containing a plurality of ball-shaped metal and/or a plurality of cylindrical-shaped metal and/or a plurality of cube-shaped metal and/or a plurality of block shaped metal.

2. A universal KE-projectile according to claim 1 , wherein the projectile tip as well as the exterior penetrator and the projectile sleeve encircling the central penetrator are aluminum.

3. A universal KE-projectile according to claim 1 , wherein the projectile tip is formed from injected or injectable material including plastic.

4. A universal KE-projectile according to claim 3 , wherein the plastic is a fiber reinforced thermal plastic.

5. A universal KE-projectile according to claim 1 , wherein the exterior penetrator and a projectile shell encircling the central penetrator are plastic or a combination of plastic and steel or aluminum.

6. A universal KE-projectile according to claim 5 , wherein the plastic is a fiber reinforced thermal plastic.

7. A universal KE-projectile according claim 1 , wherein the metal is fixed in the external penetrator by means of plastic.

8. A method for manufacturing a projectile according claim 1 with the following steps;

centering the central penetrator with or without an end penetrator and its sub-projectiles,

connecting the external penetrator with the sub-projectiles around the central penetrator,

fixing the sub-projectiles of the external penetrator by means of plastic, and

producing a projectile sleeve which at least in the external penetrator region is thin.

9. A method according to claim 8 characterized in that the plastic for fixing the sub-projectiles in the exterior penetrator is injected from the projectile tip.

10. A method according to claim 8 characterized in that the plastic is also injected from the tail side.

11. Use of the projectile of claim 1 in a munition.

12. A universal KE-projectile comprising:

a projectile tip;

a projectile sleeve;

a projectile tail end including a central penetrator;

an exterior penetrator having a curved or banana shape, the exterior penetrator being connected around the central penetrator and containing a plurality of ball-shaped metal and/or a plurality of cylindrical-shaped metal and/or a plurality of cube-shaped metal and/or a plurality of block shaped metal; and

a final penetrator at a rear part of the central penetrator including a ball-shaped metal and/or cylinder-shaped metal.

13. A universal KE-projectile according to claim 12 , wherein the projectile tip as well as the exterior penetrator and the projectile sleeve encircling the central penetrator are aluminum.

14. A universal KE-projectile according to claim 12 , wherein the projectile tip is formed from injected or injectable material including plastic.

15. A universal KE-projectile according to claim 14 , wherein the plastic is a fiber reinforced thermal plastic.

16. A universal KE-projectile according to claim 12 , wherein the exterior penetrator and a projectile shell encircling the central penetrator are plastic or a combination of plastic and steel or aluminum.

17. A universal KE-projectile according to claim 16 , wherein the plastic is a fiber reinforced thermal plastic.

18. A universal KE-projectile according claim 12 , wherein the metal is fixed in the external penetrator by means of plastic.

19. Use of the projectile of claim 12 in a munition.
