Projectile with expanding medium
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.
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.
