Abstract

The invention also relates to a method of manufacturing and use of the ammunition round in other more conventional weapon systems than the said electrothermal and/or electrothermochemical weapon systems.

Claims (24)

1. A complete ammunition round intended to be loaded as a coherent unit, the complete ammunition round comprising:

a block powder propellant charge comprising a projectile arranged on a front end thereof and a bottom piece arranged on a rear end thereof,

wherein the block powder propellant charge is for propulsion of the projectile through a barrel;

a firing device arranged on the bottom piece of the block powder propellant charge;

an elongate inner component arranged on or in close proximity to the projectile and mounted on the firing device through the block powder propellant charge,

wherein the block powder propellant charge is a load-absorbing propellant charge, and

wherein the block power charge and the elongate inner component have sufficient rigidity for bearing a load; and

an external, insulating surface, coating and/or application which is of insufficient rigidity to bear the load;

wherein the complete ammunition round is caseless.

2. The complete ammunition round according to claim 1 , wherein the elongate inner component comprises a load-transferring element anchored firmly between the projectile and the firing device.

3. The complete ammunition round as claimed in claim 1 , wherein the elongate inner component comprises a combustible material.

4. The complete ammunition round according to claim 1 , wherein the block power propellant charge is attached to the elongate inner component via an adhesive connection.

5. The complete ammunition round according to claim 1 , wherein the block powder propellant charge is arranged so as to engage in at least a rear part of the projectile and/or a front part of the bottom piece.

6. The complete ammunition round according to claim 1 , wherein the block powder propellant charge comprises a multi-perforated progressive block powder.

7. The complete ammunition round according to claim 1 , wherein the block powder propellant charge comprises a plurality of part elements which are joined together by means of a binder to form a finished, cartridge-shaped block powder propellant charge.

8. The complete ammunition round according to claim 1 , wherein the insulating surface comprises a non-load-bearing, at least outer, shrink film.

9. The complete ammunition round according to claim 1 , wherein the insulating coating comprises a non-load-bearing dimeric or polymeric raw material comprising hydrocarbons.

10. The complete ammunition round according to claim 1 , wherein the application comprises painting or other covering by means of a solution or emulsion.

11. The complete ammunition round according to claim 1 , wherein the external, insulating surface, coating and/or application is moisture-repellent or moisture-proof.

12. The complete ammunition round according to claim 1 , wherein the external, insulating surface, coating and/or application is electrically insulating.

13. The complete ammunition round according to claim 1 , wherein the external, insulating surface, coating and/or application covers all sides of the propellant charge.

14. The complete ammunition round according to claim 1 , wherein the bottom piece is made a combustible material.

15. The complete ammunition round according to claim 1 , wherein the firing device comprises a plasma torch.

16. The complete ammunition round according to claim 1 , wherein the firing device comprises a fuse.
