Abstract

A projectile that extends in the longitudinal direction and can be introduced into a cartridge by means of a casing. Moreover, the projectile has a projectile body that contains both a penetrator and an expanding medium. Characterizing the present invention, it is proposed to use metal foam, in particular air-foamed aluminum, as the expanding medium.

Claims (16)

1. A projectile that extends in a longitudinal direction, the projectile comprising:

a projectile base that at least partially accommodates a projectile body;

a penetrator that is supported inside the projectile body;

an expanding medium arranged within the projectile body, the expanding medium being a metal foam; and;

a cap that is arranged at an end of the projectile body.

2. The projectile according to claim 1 , wherein the projectile base shields the projectile body with regard to a propellant charge.

3. The projectile according to claim 1 , wherein a material of the projectile body has a higher density than the expanding medium.

4. The projectile according to claim 1 , wherein a material of the penetrator has a higher density than the expanding medium.

5. The projectile according to claim 1 , wherein a material of the projectile body has a higher density than the cap.

6. The projectile according to claim 1 , wherein the expanding medium contains pores that are adapted to be filled with a compressible fluid.

7. The projectile according to claim 6 , wherein the compressible fluid is compressed to the point of plasma formation.

8. The projectile according to claim 1 , wherein the penetrator is made of tungsten or a tungsten alloy or a tungsten-containing substrate.

9. A cartridge comprising:

a projectile according to claim 1 ;

a casing that encloses the projectile; and

a primer that is at least partially arranged in the housing.
