An improved geometric propellant loading configuration for high velocity, large or medium caliber projectile ammunition is disclosed. The propellant system includes several mutually contiguous extrudable stick shapes that in concert result in highly efficient use of propellant load space. The system reduces loading, assembling and packing (LAP) labor and overall cost, yet provides a dense pattern to increase propellant load and high perforation to improve burning progressivity over prior stick loads and more reliable and improved ballistic performance.

La présente invention a pour objet une configuration améliorée pour le chargement de poudre propulsive pour projectiles de haute vélocité dans les munitions de gros calibre et de calibre moyen. Le système de propulsion comporte plusieurs bâtons d'explosif plastique extrudable de formes mutuellement compatibles, dont l'agencement se traduit par une utilisation haute efficacité de l'espace de chargement du propulsif. Le système permet de réduire les frais généraux ainsi que les besoins de main-d'oeuvre de chargement, d'assemblage et de conditionnement, en plus d'offrir une configuration de forte densité permettant une augmentation de la charge de propulsif ainsi que l'obtention d'un haut degré de perforation, une progressivité de la combustion améliorée par rapport aux charges de bâtons antérieures, et un rendement balistique supérieur et plus fiable.
