Abstract

A combustible cartridge assembly is described. The assembly of one embodiment includes a projectile, a body having a first end portion coupled to the projectile and a second end portion opposite the first end portion. The body is made of a combustible material configured to be consumed upon firing the ammunition round assembly. A sleeve is at least partially contained within the base. The sleeve has a free end portion radially to adjacent to and coupled to the second end portion of the body. The sleeve and the body defines an interior area configured to contain a combustible propellant. A non-combustible base at least partially is coupled to the sleeve and is adjacent to the second end portion of the body.

Claims (31)

1. An ammunition round assembly, comprising:

a projectile;

a base;

a body having a first end portion coupled to the projectile and a second end portion opposite the first end portion and adjacent to the base, the body being made of a material configured to be consumed upon firing the ammunition round assembly;

a propellant; and

a sleeve at least partially contained within the base and having a free end portion radially adjacent to and coupled to the second end portion of the body, the sleeve and the body defining an interior area configured to contain the propellant, wherein the sleeve includes a dome portion having a primer hole therein, and the assembly further comprises a retention device inside the sleeve for retaining the sleeve in the base.

2. The ammunition round assembly of claim 1 wherein the second end portion of the body and the free end portion of the sleeve are arranged in a lap joint configuration.

3. The ammunition round assembly of claim 1 wherein the base is at least partially in contact with the second end portion of the body.

4. The ammunition round assembly of claim 1 wherein the base includes a flexible band adjacent to the second end portion of the body.

5. The ammunition round assembly of claim 1 wherein the base has an opening defined by an edge, the sleeve extends through the opening, and wherein the edge is immediately adjacent to the second end portion of the body.

6. An ammunition round assembly, comprising:

a projectile;

a base;

a body having a first end portion coupled to the projectile and a second and portion opposite the first end portion and adjacent to the base, the body being made of a material configured to be consumed upon firing the ammunition round assembly;

a propellant; and

a sleeve at least partially contained within the base and having a free end portion radially adjacent to and coupled to the second end portion of the body, the sleeve and the body defining an interior area configured to contain the propellant;

wherein the base includes a generally cylindrical metallic base portion and a sealing ring, the sealing ring substantially radially aligned with the second end portion of the body.

7. The ammunition round assembly of claim 1 wherein the free end portion of the sleeve and the body form a lap joint at the second end portion of the body.

8. The ammunition round assembly of claim 1 wherein the free end portion of the sleeve comprises one or more features selected from the group consisting of a scallop, a hole, a notch, and a slit.

9. The ammunition round assembly of claim 1 wherein the sleeve is made of a material configured to be consumed upon firing the ammunition round assembly.

10. A combustible ammunition round assembly, comprising:

a body having a first end portion configured for engaging a projectile and a second end portion opposite the first end portion, the body being made of a material configured to be consumed upon firing the ammunition round assembly;

a base having an edge adjacent to the second end portion of the body, the base and the body defining an internal space;

an engagement member made of a consumable material and positioned to interconnect the body and the base, the engagement member being substantially within the internal space, wherein the engagement member includes a dome portion positioned within the base and having a primer hole therein; and

a retention device inside the engagement member for retaining the engagement member in the base.

11. The ammunition round assembly of claim 10 wherein the engagement member forms a lap joint with each of the base and the body.

12. The ammunition round assembly of claim 1 wherein the base has a mounting feature configured to attach to an ignition device, and the retention device is connected to the mounting feature.

13. The ammunition round assembly of claim 12 wherein the retention device securely retains the dome portion of the sleeve between the retention device and the base.

14. The ammunition round assembly of claim 12 , further comprising a primer attached to the mounting feature and extending through the base and the primer hole in the dome portion of the sleeve.

15. The ammunition round assembly of claim 1 , further comprising a consumable protective coating on an external surface of the body.

16. The ammunition round assembly of claim 2 wherein the second end portion and the free end portion of the sleeve are arranged in a lap joint configuration between and outer surface of the sleeve and an inner surface of the body.
