Abstract

The present invention relates to a counter mass container ( 2 ) enclosing a plurality of parallel axially extending channels ( 1 ). The invention also relates to an assembly of a plurality of such counter mass containers ( 2 ). The invention also relates to a weapon comprising a barrel ( 5 ) accommodating such an assembly.

First claim

The invention claimed is:

1. Counter mass container ( 2 ) enclosing a plurality of parallel axially extending channels ( 1 ) surrounding cores ( 8 , 10 ) of the counter mass container ( 2 ), the counter mass container ( 2 ) being configured to be arranged in a barrel.

2. Counter mass container ( 2 ) according to claim 1 containing a counter mass material.

3. Counter mass container ( 2 ) according to claim 1 , wherein an axial length of the counter mass container ranges from 30 to 150 mm.

4. Counter mass container ( 2 ) according to claim 1 , wherein a radial length of the counter mass container ranges from 6 to 12 cm.

5. Counter mass container ( 2 ) according to claim 1 , wherein the diameter of the channels ( 1 ) ranges from 5 to 30 mm.

6. Counter mass container ( 2 ) according to claim 1 , wherein the channels have channel walls having a thickness ranging from 0.1 mm to 2 mm.

7. Counter mass container ( 2 ) according to claim 1 , wherein a ratio of an axial length of the counter mass container to a radial length of the counter mass container ranges from 0.3 to 2.

8. Counter mass container ( 2 ) according to claim 1 , wherein a surrounding wall encloses the channels ( 1 ).

9. Counter mass container ( 2 ) according to claim 1 , wherein the channels ( 1 ) have a hexagonal cross section.

10. Counter mass container ( 2 ) according to claim 1 , wherein the container is made of a polymeric material.

11. Assembly of a plurality of counter mass containers ( 2 ) according to claim 1 .

12. Assembly according to claim 11 , wherein from 2 to 100 containers are comprised.

13. Assembly according to claim 11 , wherein at least one propellant container ( 3 ) is arranged between said plurality of counter mass containers ( 2 ).

14. Assembly according to claim 11 , wherein at least one counter mass container ( 2 ) and at least one propellant container ( 3 ) are arranged adjacent to one another.

15. Assembly according to claim 1 , wherein a fuse is arranged to ignite a propellant contained in at least one propellant container arranged between a projectile and the counter mass container.

16. Assembly according to claim 11 , further comprising at least one propellant container ( 3 ).

17. Weapon comprising a barrel ( 5 ) accommodating an assembly according to claim 11 .

18. Counter mass container ( 2 ) enclosing a plurality of parallel axially extending channels ( 1 ) surrounding cores ( 8 , 10 ) of the counter mass container ( 2 ), wherein a fuse is arranged to ignite a propellant contained in at least one propellant container arranged between a projectile and the counter mass container.

19. Weapon comprising a barrel ( 5 ) accommodating an assembly of a plurality of counter mass containers ( 2 ) each enclosing a plurality of parallel axially extending channels ( 1 ) surrounding cores ( 8 , 10 ) of the counter mass container ( 2 ).
