Abstract
A shatter resistant armor-piercing military projectile is disclosed. The struction comprises a plurality of high strength metallic lamellae interconnected with a high ductility alloy selected to provide an impact energy management system capable of maintaining the projectile's structural integrity during adverse operating conditions, such as oblique impact on spaced or solid armor targets.
Claims2
An armor-piercing military projectile of the solid type, comprising a central core (16) nested within a plurality of concentric metallic lamellae (10);
- each of said core and lamellae having an outer circular cylindrical side surface merging into an axial ogive termination at the projectile front end;
- each lamellae being a hollow annular shell structure having a substantially uniform wall thickness therealong;
- said lamellae and core terminating at a common transverse plane at the rear end of the projectile;
- copper bonding material fused to the core and lamellae surfaces along each entire interface;
- the lamellae being of decreasing hardness and increasing toughness measured from the outermost lamellae to the innermost lamellae;
- the outermost lamellae being a quenchhardened steel providing a relatively hard outer surface along the entire length of the projectile.
