摘要
Abstract
Samples of RDX-CMDB propellents containing catalysts with RDX replaced by guanidinium azotetrazolate ( GZT) were prepared using slurry casting technique. The influences of GZT on combustion behaviors of RDX-CMDB propellants including burning rates, pressure exponents and flame structure were studied, and the reasons for the difference of combustion behaviors between propellants with catalysts and without catalysts were analyzed. The thermal behaviors of propellants were analyzed through the difference scanning calorimeter( DSC). Results indicate that GZT has great effects on flame temperature, width of dark zone, numbers of lighting point on the combustion surfaces and temperature gradient of combustion surface to condensed phase. The burning rates of propellants decrease with the increase in GZT content under pressure ranging from 1 Mpa to 10 Mpa,while pressure exponents increase. In the DSC curve of propellants containing GZT and catalysts, a new independent decomposition peak corresponding to decomposition of GZT appears, and the first decomposition peak temperature decreases with addition of GZT into propellant.关键词
