Feasibility Study on a Multi-Component Propellant System for 30 MM Ammunition
Abstract
Using the 30 mm WECOM with a 3400 grain projectile as a test vehicle, a study was made to determine the feasibility of employing a novel propellant concept to attain maximum projectile velocity within the constraints of a 40,000 to 50,000 psi chamber pressure range. The propellant system considered, referred to as the MAGNUM Concept, consisted of a blend of BALL POWDERS in granular and pelleted form. This combination of granular and compacted propellants readily permitted a 20% increase in propellant charge weight. To obtain maximum performance improvement from the increase in propellant charge weight, the pelleted component was surface coated with a polymer to delay ignition and initial forward movement of the projectile was facilitated by providing a free run section the gun chamber. The net effect of these two modifications was to reduce peak chamber pressure and extend the propellant burn time thereby increasing the piezometric efficiency of the system.
