A basic requisite for simulation based analysis is that the models used are based on well determined mateial data and that experiments are used to determine the data on which the simulations will be based. In this report we present a rst analysis of a propellant charge module of type DM72, that is used by the Swedish defence in Archer. The module is presented together with performance calculations representative of Archer. The module has been dismantled and measured. The measurements have been compared to previously published material.
