Abstract:

A modular artillery charge system consists of two distinct solid propellant harge modules. Each module consists of a three-piece combustible cartridge case design and bi-directional center core core ignition system. The three-piece combustible cartridge case consists of a combustible case body, having an open end and a end; a cap, having a closed end and an open end; and a center tube. The closed ends of the body and the cap have a hole in the center. The center core tube is positioned longitudinally through the combustible case body, and contacts the closed ends of both the cap and the body. The bi-directional center core ignition system comprises a core igniter bag and two end igniter bags. The core igniter bag occupies the center core tube, and the end igniter bags contact the core igniter bag. The bi-directional center core ignition system may be ignited by percussion primers or a laser ignition system.
