Anti-armor warhead assembly

Abstract

An anti-armor warhead assembly includes an open-ended cylindrical warhead se defined by a first section, a second section and a third section. The first section has a constant inside diameter D 1 . The second section has a constant inside diameter D 2 and connects the first section and the third section. The third section is defined by an inside diameter D 3 . The relationship between the diameters is such that D 1 <D 3 ≦D 2 . A hollow conically shaped charge liner is axially aligned and fitted within the warhead case. Explosive material fills the first section of the warhead case about an outwardly facing surface of the charge liner. A retaining ring fitted on the third section retains the charge liner and the explosive material in the first section. An end cap fitted to the first section has an initiator coupler formed therein for housing a primer charge used to detonate the explosive material.

What is claimed as new and desired to be secured by Letters Patent of the United States is: 
     
       1. An anti-armor warhead assembly, comprising: an open-ended cylindrical warhead case for structurally supporting said warhead assembly in flight, said warhead case defined by a first section, a second section and a third section, said first section having a constant inside diameter D 1 , said second section having a constant inside diameter D 2 , said second section further being between and connecting said first section and said third section, and said third section defined by inwardly facing threads presenting an inside diameter D 3 , wherein D 1  <D 3  ≦D 2  ;   a hollow conically shaped charge liner axially aligned and fitted within said warhead case, said charge liner having a closed apex and an open base opposite said closed apex, said charge liner further defining an inwardly facing surface and an outwardly facing surface;   explosive material filling said first section of said warhead case about said outwardly facing surface of said charge liner;   a retaining ring threadably engaging said inwardly facing threads of said third section for retaining said charge liner and said explosive material in said first section; and   an end cap fitted to said first section, said end cap having an initiator coupler formed therein for housing a primer charge used to detonate said explosive material, said initiator coupler being in axial alignment with said charge liner.   
     
     
       2. An anti-armor warhead assembly as in claim 1 wherein said open base of said charge liner defines an annular lip extending radially outward from said charge liner to engage said second section of said warhead case.
