不同纳米材料含量对RDX-CMDB推进剂燃烧性能的影响
Effects of Different Content of Nanomaterials on the Combustion Performance of RDX-CMDB Propellants
摘要
Abstract
The influence of nano-copper (n-Cu) ,nano-nickel (n-Ni) and carbon nanotubes on the combustion performance of RDX-CMDB propellants was investigated .The mechanism of n-Ni on the combustion performance was also discussed by analysis of flame morphology and thermal decomposition performance .The results reveal that n-Ni with mass ratio of 0 .6％ would re-duce the pressure exponent of RDX-CMDB propellant from 0 .29 to 0 .11 in the pressure range of 6-16MPa .By contrast ,the effect was not obvious for the 0 .2％ n-Cu ,which even causes the decrease of burning rate at 2MPa and 8-16MPa .For the 0 .8％ CNTs with conventional Pb-Cu-C as catalyst , the burning rate of RDX-CMDB propel ant increases from 17 .12 to 22 .12mm/s at 10MPa .Furthermore ,The thermal decomposition and flame morphology imply that n-Ni improves the decom-position heat ,enhances the burning surface temperature and thermal feedback ,which is contributed to the thermal decomposi-tion rate .关键词
