ABSTRACT:
A method of assembling a shaped charge projectile employing a fluted liner includes the steps of, first, loading an explosive propellant material in a hollow projectile case, next, preforming a shaped cavity in the propellant material, then, loading a fluted hollow linear into the cavity and, finally, consolidating the propellant material in the projectile case. The consolidation is carried out by engaging the liner with an interface sleeve mounted on an end of a punch and applying consolidating pressure against the propellant material via the sleeve and the liner. The sleeve is composed of resiliently-yieldable and deformable elastomer material having an original shape similar to that of the hollow interior of the liner but without any flutes formed thereon which would match the fluted liner. The consolidating pressure causes the material of the sleeve to deform into a configuration which matches that of the fluted liner but without damaging the same and returns back to its original shape when the pressure is released.
