Patent Images
1. A duplex round comprising:
- a tubular projectile of a dense material adapted for target penetration and having a central axial bore;
a sub-diameter projectile held within said axial bore throughout its length and configured to be an obturator for said tubular projectile; and
bonding material between said sub-diameter projectile and said tubular projectile and adapted to form a seal therebetween which is compressable during the interior ballistic phase of projectile flight and releases during aerial flight to permit separation of the two projectiles.

Abstract
A duplex projectile to be fired from a gun bore is made up of a tubular pectile and a conical shaped projectile fastened within the tubular projectile by means which are capable of withstanding acceleration forces on the round while the round is within the bore after being fired but which release the conical projectile from the tubular projectile once the two exit from the bore.

8. A duplex round comprising:
-
a tubular projectile having a central axial bore; a sub-diameter projectile having a depleted uranium nose and a light pyropheric base end with a first hollowed-out portion in the base end and second, inside, hollowed-out portion adapted to hold incendiary material forward from said first hollowed-out portion and an opening connecting said first and second hollowed-out portions; and bonding material between said sub-diameter projectile and said tubular projectile adapted to form a seal therebetween which is compressable during the interior ballistic phase of projectile flight but releases during aerial flight to permit separation of the two projectiles. - View Dependent Claims (9, 10)
