Abstract: Through burning rate experiments and thermal analysis, the influence of adding three forms of carbon: carbon black, C 60 and fullerene soot separately in double based propellants was studied By AM1 quantum chemistry method, the system energy change of fullerne and NO interaction was calculated Results show that C 60 and fullerene soot can enhance the burning rate of double based propellants, broaden the plateau region and lower the concentration of NO x in gas products From analysis of molecular structure of fullerene and its bonding ability by molecular orbital theory,the catalytic mechanism of Pb xC 60 active sites was posed to explain why C 60 and fullerene soot have better catalytic effects than carbon black in Pb Cu Carbon black catalytic system in double based propellants
