采用激光粒度分析仪、扫描电子显微镜/光电子能谱(SEM/EDS)和X-射线衍射仪研究了CL-20取代Al/HMX-XLDB推进剂中HMX对推进剂凝聚相燃烧产物粒径、形貌以及组成的影响.研究表明,CL-20替代推进剂中的HMX可提高推进剂中Al粉的燃烧效率.CL-20完全取代推进剂中HMX时,推进剂燃烧残渣率最低,为0.500%,但HMX/CL-20-XLDB推进剂燃烧残渣率则为1.784%,分析可能与推进剂燃烧凝聚相产物团聚效应有关.随着CL-20的加入,在推进剂燃烧凝聚相产物中出现了κ-Al2O3和δ-Al2O3等Al的亚稳态氧化物.
The particle size of combustion products of condensed phase propellant in HM-CL-20 substituted Al / HMX-XLDB propellants was studied by laser particle size analyzer, SEM / EDS and X-ray diffractometer. Appearance and composition of the propellant.The research shows that HMX in the alternative propellant CL-20 can improve the combustion efficiency of the Al powder in the propellant.When the CL-20 completely replaces the HMX in the propellant, the propellant combustion residue rate is the lowest, 0.500% , But the combustion residue rate of HMX / CL-20-XLDB propellant was 1.784%, which may be related to the agglomeration effect of propellant combustion condensed phase products.With the addition of CL-20, κ-Al 2 O 3 and δ-Al 2 O 3 and other metastable oxides.
