Dual-mode Projectile

Abstract

A projectile for acceleration and delivery to a target having a jacket having rear surface, a cylindrical side surface, and a tapered rupturable front surface with a cavity between the surfaces, a core disposed within the cavity, and a mantel packing the core within the cavity, wherein the core is comprised of a denser material than material comprising the jacket, the front surface ruptures upon impact to a target, and the core is ejected through the ruptured front surface to penetrate the target.

What is claimed is: 
     
         1 . A projectile for acceleration and delivery to a target comprising:
 a jacket having rear surface, a cylindrical side surface, and a tapered rupturable front surface defining a cavity between the surfaces;   a core disposed within the cavity; and   a mantel packing the core within the cavity;   wherein the core is comprised of a denser material than material comprising the jacket, the tapered front surface is formed to rupture on impact at a minimum momentum such that the core is ejected through the ruptured front surface to penetrate the target.   
     
     
         2 . The projectile as set forth in  claim 1  wherein the core has a diameter smaller than a diameter of the cavity. 
     
     
         3 . The projectile as set forth in  claim 1  wherein the jacket comprises a copper jacket. 
     
     
         4 . The projectile as set forth in  claim 1  wherein the jacket comprises a brass jacket. 
     
     
         5 . The projectile as set forth in  claim 1  wherein the jacket comprises a steel jacket. 
     
     
         6 . The projectile as set forth in  claim 1  wherein the core comprises a tungsten core. 
     
     
         7 . The projectile as set forth in  claim 1  wherein the core comprises a depleted uranium core. 
     
     
         8 . The projectile as set forth in  claim 1  wherein the core comprises a front surface having a point. 
     
     
         9 . The projectile as set forth in  claim 1  wherein core further comprises one or more frangible components which separate upon penetration to the target. 
     
     
         10 . The projectile as set forth in  claim 9  wherein the frangible components comprise one or more fleschettes. 
     
     
         11 . A method of manufacturing a projectile for acceleration and delivery to a target comprising:
 forming a jacket having rear surface, a cylindrical side surface, and a tapered front surface defining a cavity between the surfaces;   disposing a core within the cavity; and   packing the core by a mantel within the cavity;   wherein the core is comprised of a denser material than material comprising the jacket, the tapered front surface is formed to rupture on impact at a minimum momentum such that the core is ejected through the ruptured front surface to penetrate the target.   
     
     
         12 . The projectile as set forth in  claim 11  wherein the core has a diameter smaller than a diameter of the cavity. 
     
     
         13 . The projectile as set forth in  claim 11  wherein the jacket comprises a copper jacket. 
     
     
         14 . The projectile as set forth in  claim 11  wherein the jacket comprises a brass jacket. 
     
     
         15 . The projectile as set forth in  claim 11  wherein the jacket comprises a steel jacket. 
     
     
         16 . The projectile as set forth in  claim 11  wherein the core comprises a tungsten core. 
     
     
         17 . The projectile as set forth in  claim 11  wherein the core comprises a depleted uranium core. 
     
     
         18 . The projectile as set forth in  claim 11  wherein the core comprises a front surface having a point. 
     
     
         19 . The projectile as set forth in  claim 11  wherein core further comprises one or more frangible components which separate upon penetration to the target. 
     
     
         20 . The projectile as set forth in  claim 19  wherein the frangible components comprise one or more fleschettes.
