Abstract
The projectile, adapted to be fired from an automatic cannon, comprises a frangible porous brittle generally cylindrical casing having a tapered nose portion and made of a molded sintered powder material preferably consisting predominantly of 60 to 100% type 316 stainless steel powder, the remainder being pure iron powder. The rear end of the casing is formed with an axial bore wherein a hard dense penetrator rod is received, preferably made of tungsten or tungsten carbide. Behind the penetrator rod, the casing has an enlarged bore wherein an incendiary pellet is received, preferably comprising zirconium crystals molded in an epoxy matrix. A massive closure plug closes the enlarged bore behind the incendiary pellet. Upon impact with a target, the frangible casing disintegrates into granular fragments while the penetrator rod punches a hole in the target through which the fragments are propelled. The incendiary pellet is ignited by heat generated therein by molecular disruption when the pellet is compressed or forced through the hole by the massive closure plug, whereby ignited incendiary particles are energetically propelled through the hole.
