Abstract

A penetrator and a sub-caliber ammunition or projectile accommodating said penetrator. The penetrator according to the invention is characterized by the fact that the penetrator has an interface in the front area. Via said geometric interface, a basic penetrator devised in according to the invention can be provided having different penetrator tips and completed to form an individual KE penetrator.

First claim

What is claimed is:

1. A penetrator for a projectile having a sabot and a fin assembly, the penetrator comprising:
a base part, having a first interface projecting from an end of the base part; and
an attachment part having a second interface,
wherein the first interface is received in the second interface to interconnect the base part and the attachment part in a form- and/or force-fitting manner,
wherein the first interface is formed directly in front of the sabot, and
wherein a length of the first interface is 50% of a diameter of the penetrator at a location at which the first interface is received in the second interface.

2. The penetrator as claimed in claim 1 , wherein the first interface is incorporated in a front region of the base part.

3. The penetrator as claimed in claim 1 , wherein the attachment part is a penetrator tip.

4. The penetrator as claimed in claim 3 , wherein the penetrator tip is tailored to individual targets.

5. The penetrator as claimed in claim 3 , wherein the base part and the penetrator tip are formed of tungsten heavy metals, tungsten carbide, high-strength steel, copper, depleted uranium, or tantalum.

6. The penetrator as claimed in claim 3 , wherein the penetrator tip and the base part are different materials.

7. The penetrator as claimed in claim 3 , wherein the penetrator tip is provided with at least one predetermined breaking point.

8. The penetrator as claimed in claim 3 , wherein the penetrator tip is reinforced, and
wherein the reinforcement is realized only in the front tip region.

9. The penetrator as claimed in claim 1 , wherein the first interface and the second interface are configured as a threaded connection, as a bayonet connection, or as a snap connection.

10. The penetrator as claimed in claim 1 , wherein the first interface and the second interface are connected with an adhesive.

11. The penetrator as claimed in claim 1 , wherein the attachment part is one of a plurality of interchangeable attachment parts comprising:
an attachment part having a penetrator tip for an SI target;
an attachment part having a penetrator tip for an oblique target; and
an attachment part having a penetrator tip for a reactive target, and
wherein the interface is configured to interchangeably receive the attachment part having the penetrator tip for an SI target, the attachment part having the penetrator tip for an oblique target and the attachment part having the penetrator tip for a reactive target.

12. The penetrator according to claim 1 , wherein the attachment part includes multiple penetrator tips of different length.

13. The penetrator according to claim 12 , wherein the base part and the penetrator tips are modules that form the penetrator by attaching one of the penetrator tips to the base part.

14. The penetrator according to claim 1 , wherein the attachment part includes multiple penetrator tips of different length,
wherein the base part forms a shortened base penetrator, and
wherein the base part and the penetrator tips are modules that form the penetrator by attaching one of the penetrator tips to the base part.

15. A projectile comprising:
a sabot;
a fin assembly; and
the penetrator as claimed in claim 1 .

16. A projectile comprising:
a sabot;
a fin assembly; and
a penetrator, the penetrator comprising:
a base part, the base part having a first interface projecting from an end of the base part which is directly in front of the sabot; and
an attachment part having a second interface,

wherein the first interface is received in the second interface to interconnect the base part and the attachment part in a form- and/or force-fitting manner, and
wherein a length of the first interface is 50% of a diameter of the penetrator at a location at which the first interface is received in the second interface.
