Abstract
The invention relates to a method of improved ammunition production, more specifically to a cellular structure end cap, suitable for an ammunition round, said end cap comprising a porous 3D spatial structure in the shape of said end cap, wherein in said porous 3D spatial structure comprises a surface skin.
Claims20
An ammunition round, comprising:
- a cellular structure end cap, said cellular structure end cap comprising a porous three-dimensional (3D) spatial structure in the shape of said cellular structure end cap, wherein said porous 3D spatial structure comprises a surface skin, wherein the porous 3D spatial structure is a honeycomb, lattice, or foamed structure, and wherein the porous 3D spatial structure has a void fraction in the range of 30%-80%;
- a case, said case and cellular structure end cap forming a cartridge case;
- a primer cap;
- propellant;
- and
- a projectile located in said cartridge case.
