Abstract

A projectile having a projectile body for holding a penetrator, a projectile rear, and a projectile ogive. The projectile body has a narrowed point, on which the penetrator can be supported. The narrowed point results in reliable breaking open of the projectile body when the projectile hits a target.

First claim

What is claimed is:

1. A method for the production of a projectile body for a projectile, the projectile comprising a penetrator, the projectile body, a projectile stern and a projectile ogive, the method comprising:
producing the projectile body as a tube section; and
processing a surface of an inner diameter of the projectile body such that a constriction is obtained in the tube section, the constriction configured to support the penetrator,
wherein in order to produce the constriction, the surface of the inner diameter of the projectile body is processed from both front and rear sides of the projectile body, such that the inner diameter of the projectile body at the constriction is smaller than at all remaining portions of the inner diameter provided forward and rearward of the constriction, and
wherein the surface of the inner diameter of the projectile body is processed such that, with respect to an axial direction of the inner diameter, a length of the constriction is smaller than a length of each of the remaining portions of the inner diameter provided forward and rearward of the constriction.

2. The method as claimed in claim 1 , wherein the constriction is disposed in a central region of the projectile body.

3. The method as claimed in claim 2 , wherein the constriction is disposed off-center in the projectile body.

4. The method as claimed in claim 1 , wherein the constriction is formed so as to be circumferential around the inner diameter of the projectile body.
