Abstract

Through comparing the combustion process of gun propellant by dynamic interior ballistic cycle with static closedbomb test, an ideal gun propellant with special progressivity distribution is found. Based on the difference of progressivity distribution between an ideal and a real gun propellant, a quantitative assessment method of gun propellant progressivity based on closedbomb test has been proposed. The testing results show that the assessment results well accord with the data of interior ballistic cycle.

Key words
