Universal KE projectile, in particular for medium caliber munitions
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.
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.
