Abstract

A method for producing a shell and a shell produced by this method, wherein the shell has a projectile, a combustible propellant charge casing, and a casing cover that joins the propellant charge casing with the projectile, such that the projectile has a sealing ring adjacent to the casing cover. To realize cost-effective assembly of a shell of this type, the casing cover is produced as an injection molded part made of an elastic plastic, such that the front end region of the casing cover facing the projectile forms the sealing ring.

Claims

1. A method for producing a shell with a projectile, a combustible propellant charge casing, and a casing cover that joins the propellant charge casing with the projectile, where the projectile has a sealing ring adjacent to the casing cover, the method comprising the steps of:

producing the casing cover by injection molding with an elastic plastic, such that a front end region of the casing cover facing the projectile forms the sealing ring; and

joining the casing cover with the propellant charge casing and the projectile.

2. The method in accordance with claim 1, further including providing the casing cover with an annular rated break point between the region that forms the sealing ring and an adjacent rearwardly directed region of the casing cover.

3. The method in accordance with claim 1, including pressing or shrinking the region of the casing cover that fauns the sealing ring onto the projectile.

4. The method in accordance with claim 1, including fastening the region of the casing cover that forms the sealing ring to the projectile by adhesive bonding.

5. The method in accordance with claim 1, including fastening the region of the casing cover that forms the sealing ring to the projectile by a locknut.

6. A shell, comprising:

a projectile that includes a subcaliber penetrator and a discarding sabot;

a combustible propellant charge casing; and

a casing cover that joins the propellant charge casing with the sabot, wherein the sabot has a scaling ring adjacent to the casing cover, the casing cover being an injection molded part made of an elastic plastic and the sealing ring being formed by a front end region of the casing cover.

7. The shell in accordance with claim 6, wherein the sabot is a cup sabot with a plate-shaped propulsion element that acts on a rear end of the subcaliber penetrator, wherein the front end region of the casing cover that serves as the sealing ring encloses the propulsion element.

8. The shell in accordance with claim 6, wherein an annular break point is provided between the front end region of the casing cover and a remainder of the casing cover.

9. The shell in accordance with claim 6, and further comprising a locknut arranged to fasten the sealing ring to the projectile.
