Armor penetration projectile

Abstract

A projectile having an extendible nose portion which will extend the diste between the shaped charge of a projectile and the surface of the target at the time of detonation.

We claim: 
     
       1. A projectile including a shaped explosive charge within a casing, a nose cone attached to one end of the casing and means for extending the part of the nose cone remote from said casing even further from said shaped charge when said projectile is in flight. 
     
     
       2. The projectile of claim 1 wherein the cone includes a threaded tube and extending means comprises said threaded tube being mounted in a bore in said cone, said bore including means cooperating with said threads on said tube to allow said tube to reciprocate with respect to said cone. 
     
     
       3. The projectile of claim 2 wherein the tube extends both inside and outside said bore and inside and outside said cone, the portion of the tube extending outside the cone having radially extending fins mounted thereon. 
     
     
       4. The projectile of claim 3 wherein the cone includes a radially extending shoulder adjacent the inward end of the bore, the end of the tube inside the cone having a radially outwardly extending flange configured to engage said shoulder upon the outward movement of said tube. 
     
     
       5. The projectile of claim 2 wherein the cone includes a radially extending shoulder adjacent the inward end of the bore, the end of the tube inside the cone having a radially outwardly extending flange configured to engage said shoulder upon the outward movement of said tube. 
     
     
       6. The projectile of claim 2 wherein the threads on said tube are configured to accommodate the balls of a ball race mounted on the interior of said bore. 
     
     
       7. The projectile of claim 3 wherein the threads on said tube are configured to accommodate the balls of a ball race mounted on the interior of said bore. 
     
     
       8. The projectile of claim 4 wherein the threads on said tube are configured to accommodate the balls of a ball race mounted on the interior of said bore. 
     
     
       9. The projectile of claim 5 wherein the threads on said tube are configured to accommodate the balls of a ball race mounted on the interior of said bore.
