| Abstract: | In order to study the long-term storage stability of azidonitramine propellants with celluloid charge case, DSC and VST were used to analyze their chemical compatibility. Meanwhile, component migration of azidonitramine propellants and celluloid charge case were tested according to GJB736.8—1990, initiating explosive device, Method of test at 71 ℃. The results indicated that chemical compatibility between the two components is good, exothermic peak deviation is 0.5 ℃. The value of R in the vacuum stability test is 0.3 mL/g, which is less than the threshold of compatibility, 0.6 mL/g. After 26 days storage at 71 ℃, mass fraction of plasticizer in propellant (DIANP、NG) decreased from 39.82% to 33.67%, and mass fraction of plasticizer in charge case (DIANP、NG) increased from 0 to 33.89%, indicating the existence of migration phenomenon of propellant and charge case. Chemical compatibility is good, but physical stability is poor in presence of plasticizer migration. Mass fraction attained balance after 10 days’ accelerated aging. |
