摘要
Abstract
To improve the combustion performance of azidonitramine gun propellant, the sample was desensitized with the surface layer coated by small-molecule multiple alkynyl compound (TPTM) which was used as insensitive precursor with rotating-drum spraying technique.TPTM was reacted with 1,5-diazido-3-nitrazapentane (DIANP), which is component of azidonitramine gun propellant, at 60 ℃ to form macromolecule deterrent with cross-linked structure.The effect of deterrent was characterized by closed-bomb test, thermal-aging test and 14.5 mm machine gun test.The interior ballistic properties was checked by the 30 mm gun tests.Results show that initial burning rate of the deterred propellant reduces about 15%, and its progressive burning charac-ters value Lm/L0 is more than 1.5, the long-storage stability is excellent, and the interior ballistic properties in 30 mm gun is good.关键词
