Karakterisering av krutt til småkalibret ammunisjon

Abstract

Five different propellants for use in small calibre ammunitions delivered by different foreign producers have been studied with regard to grain dimensions, burning characteristics and energy content. All propellants studied have been tested in Closed Vessel and pressure measured as function of time until all propellant has burned up. For all propellants different loading densities have been tested to be able to experimentally detennine the propellant impetus. Theoretical impetus has in addition for four of the propellants been determined by use of CHEETAR Finally, a comparison between experimentally found and theoretically calculated impetuses has been carried out.
