Abstract

The invention aims at improving the quality of ammunition having a shell whose wall consists of a combustible or consumable wound body with at least one double layer of crossed threads. The wound body (1) forms a single piece. The winding density of the wound body (1) varies along the length of the wound body (1) so that distribution of the threads (3) optimally matches the charge of the shell (12).

Claims

1. Ammunition, comprising:

a case comprising a combustible or consumable wound package having an adaptation region for a projectile at a first end, an adaptation region for an end socket at a second end and a wall including at least one double layer of intersecting filaments, the filaments being impregnated or coated with a binding agent; and

an end socket containing a detonating charge connected to the adaptation region for the end socket at the second end of the wound package;

wherein the wound package is in one piece and a density of winding of the wound package is varied over a length of the wound package to match a loading of the case, the density of winding being determined by an angle of intersection of the filaments in the at least one double layer, angles of intersection of the filaments of the wound package being smaller in the adaptation region for a projectile and the adaptation region for the end socket than angles of intersection of the filaments in remaining regions of the wound case.

2. Ammunition according to claim 1, wherein the angles of intersection of the filaments in the wound package decrease continuously in directions of the adaptation region for a projectile and the adaptation region for the end socket.

3. Ammunition according to claim 1, wherein the wound package comprises several double layers and wherein angles of intersection of the filaments in the respective double layers differ from one another.

4. Ammunition according to claim 1, wherein the filaments form a braided network within each double layer of the wound package.

5. Ammunition according to claim 1, wherein the binding agent includes an explosive substance admixed therein.

6. Ammunition according to claim 1, wherein interstices between the filaments are filled at least partially with an explosive substance.

7. Ammunition according to claim 1, wherein the adaptation region for a projectile has a flange at the first end into which a projectile body can be force fit.

8. Ammunition according to claim 7, wherein the flange comprises a thickening of the wound package formed from additional filament layers deposited predominantly parallel to one anther on the wound package.

9. Ammunition according to claim 1, further comprising at least one sealing ring arranged concentrically in relation to an axis of the ammunition on the end socket outside the adaptation region for the end socket.

10. Ammunition according to claim 1, further comprising a projectile connected to the adaptation region for a projectile of the wound package, at least a part of the projectile extending within the case.

11. Ammunition according to claim 10, further comprising a projectile-receiving adapter matched to and receiving the projectile integrated within the wound package in the adaptation region for the projectile.
