Ballistic Evaluation of 19-Perforation Propellant in the 155-mm Propelling Charge, M203E1
Abstract
Top-zone propelling charges for the Army 155-mm Howitzer were manufactured using 19-perforation, M30A1, granular propellant and tested against M203E1 Propelling Charges employing standard 7-perforation propellant. Velocities, chamber pressures, pressure wave levels, and ignition delays were essentially equivalent for the two charges when fired at ambient temperatures or after cold conditioning. Significant differences in performance, however, were exhibited by the two charges when fired hot.
