摘要
通过燃速测定、差示扫描量热技术(DSC)和热失重技术(TG)研究了有机金属化合物(OME)对二硝酰胺铵(ADN)单元推进剂的热分解和燃烧性能的影响.1～12 MPa范围内,1%OME可以提高ADN单元推进剂的燃速.TG和DSC分析表明,OME可以显著降低ADN的起始分解、放热温度;OME含量对ADN的起始热分解温度有明显的影响.热分解动力学分析显示,加入1%OME后,ADN的热分解活化能降低30%左右.
The effect of organ-metallic compound OME on the combustion and thermal decomposition of ammonium dinitramide （ADN） was investigated by burning rate measurement, DSC and TG. It is shown that C）ME can increase the burning rate of ADN within the pressure intervals of 1～ 12 MPa. TG and DSC tests for ADN and ADN＋1%OME indicate that the initial decomposition temperature of ADN can be decreased by the addition of OMEnoticeably. Furthermore the initial decomposition temperature of ADN is subject to the content of OME evidently. Kinetic analysis for DSC and TG data show that the activation energy of thermal decomposition of ADN has been decreased by about 30% by the addition of 1% OME to ADN.
