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.
Claims16
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.
