利用燃速和火焰结构测试、TG-DTG和高压DSC实验分别研究了含1,3,3-三硝基氮杂环丁烷(TNAZ)的两类(TZ-CMDB和TZ-NEPE)推进剂的燃烧性能和热行为,发现了TNAZ对推进剂燃速、压力指数和火焰结构的影响及高压下TNAZ对上述两类推进剂中其它含能组分分解的影响,并得出常压下TZ-CMDB和TZ-NEPE推进剂受热时,TNAZ挥发和分解的温度范围为58～190℃。
Two classes of TZ-CMDB and TZ-NEPE propellants with 1,3,3-trinitroazetidine (TNAZ) were studied using the combustion and flame structure tests, TG-DTG and high- The effects of TNAZ on the burning rate, pressure index and flame structure of propellants and the effect of TNAZ on the decomposition of other energetic components in the above two propellants under high pressure were investigated. The results show that under normal pressure, TZ The temperatures at which TNAZ volatilizes and decomposes when the CMDB and TZ-NEPE propellants are heated, ranging from 58 to 190 ° C.
