The effect of different aging times (1 day, 3 days, 5 days and 7 days) on the combustion performance and mechanical properties of nitroguanidine propellants was studied.Through the mechanical properties test of impact and compression and closed bomb test of the prepared propellants, it was found that the relative steepness of the propellants aged for 3 days under normal and low temperature conditions was all less than 1;Under normal and low temperature conditions, the impact strength of propellants aged for 5 days was the largest;Propellants aged for 7 days had the highest compressive strength at low temperatures and propellants aged for 1 day had the highest compression rate at low temperatures.Comprehensive research results show that aging time of three days has a better improvement in the combustion performance and mechanical properties of the propellants.
Key words: aging process / combustion and mechanical performance / nitroguanidine propellants
