Two kinds of desensitized propellants 1,5-diazido-3-nitrazapentane (DIANP) propellant and high-energy nitramine propellant) were desensitized with polymer deterrent NA in water medium. The migrations of NA deterrent in two kinds of propellants were investigated by accelerated aging tests,closed-bomb tests and interior ballistic tests respectively. The concentration profiles of deterrent NA in two kinds of propellants before and after long-term storage were studied by FTIR microspectroscopy. Results show that there are not significant changes in the explosion heat,p-t curves,interior ballistic and the concentration profiles. The migration ability of NA deterrent is weak in DIANP and nitramine propellants. The propellants desensitized by polyester NA should be stable in the interior ballistic.
