ESTABLISHMENT OF CHARGE WEIGHTS FOR CHARGE, PROPELLING, 155-MM, XM51E1,

Abstract

Tests were conducted to establish charge weights for charge, dual-granulation, XM5151 for the 155-mm howitzer, T258. The M17 propellant tested consisted of a single-perforated propellant for the base charge and a multiperforated propellant for charges 2 through 6. In the early phases of the test, the single-perforated propellant produced very erratic chamber pressures when fired with the zone 6 charge. To establish a satisfactory propelling charge, lot PA-E-31526 was replaced with a previously tested, multiperforated, M17 propellant. Using the multiperforated propellant (web 0.019 inch) in zone 1, and 0.0576-inch-web propellant in zones 2 through 6, a satisfactory charge establishment was completed at normal and extreme temperature. The single-perforated propellant was considered satisfactory for use only as a zone 1 charge. (Author)
