Abstract

Abstract A penetrating member for a projectile comprising a cylindrical mass body e from a high-density material and formed with a hardened front end in the form of a concavely curved scoop with an outstanding spike in its center. One end of a tubular liner abuts the scoop, the liner being made of an easily deformable, material. When the liner hits a target, the liner is forced back along the curve of the scoop and out the center of its tubular form as a high-velocity, target-penetrating jet of material.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 95 words
A penetrating member for a projectile comprising: a cylindrical mass body made from a high-density material with a front end in the form of a concavely curved scoop with an outstanding spike in the center of the scoop; and a tubular liner made from easily deformable material, one end of said liner abutting the scoop of said mass body, so that, when the liner hits a target, the liner is driven back along the curve of said scoop and then forward around the spike to form a high-velocity jet of material which penetrates the target.
Claim 2
Dependent Claim 95 words
A penetrating member for a projectile comprising: a cylindrical mass body made from a high-density material with a front end in the form of a concavely curved scoop with an outstanding spike in the center of the scoop; and a tubular liner made from easily deformable material, one end of said liner abutting the scoop of said mass body, so that, when the liner hits a target, the liner is driven back along the curve of said scoop and then forward around the spike to form a high-velocity jet of material which penetrates the target.
Claim 3
Dependent Claim 23 words
A penetrating member as in claim 1, wherein the density of said liner is at least as great as the density of aluminum.
Claim 4
Dependent Claim 22 words
A penetrating member as in claim 1, wherein the length of the spike is less than half the length of the liner.
Claim 5
Dependent Claim 22 words
A penetrating member as in claim 1, wherein the length of the spike is greater than half the length of the liner.
