摘要
研究了硼氢化合物 B1 2 H1 2 [N(C2 H5 ) 4] 2 对 NEPE推进剂燃烧性能的影响 ,采用 DSC分析了 B1 2 H1 2 [N(C2 H5 ) 4] 2 与 NEPE推进剂主要组分硝酸酯的相容性以及对推进剂固化反应的催化作用和对高氯酸铵、硝胺常压热分解的催化作用 ,并利用恒压静态燃速仪测试了推进剂在 4～ 1 1
The effect of B12H12［N(C2H5)4］2 (YL-6) on combustion property of NEPE solid propellant was studied. The compatibility of YL-6 and nitrate ester, the effect of YL-6 on the curing reaction and on the thermal decomposition behavior of ammonium perchlorate and nitroamino-compounds were studied by Differential Scanning Calorimetry (DSC). It was observed that YL-6 exhibited not so good compatibility with nitrate ester which accelerated the thermal decomposition of nitroamino-compounds but had little effect on ammonium perchlorate and on the curing reaction. When YL-6 was applied to NEPE solid propellant, the burning rate of propellant increased comparing to plumbean citrate as burning rate catalyst and the pressure exponent was effectively brought down to 0.13 in high pressure which was called platform phenomenon.
