Abstract: |
The particle size and distribution of particle size of Mg/Al were analyzed by Mastersizer. The thermal characterisitics of CDMB propellant were analyzed by TG-DSC. The flame structure was studied by using the burning device and the differences of the flame structure were compared amongst CMDB, Al-CMDB, Mg-CMDB and Mg/Al-CMDB propellants. The surface appearance of the propellant quenched and surface composition were researched by the SEM and EDS. The results show that the Mg/Al alloy has a peak 630.3℃ of the heat of CMDB propellant. The combustion condition of CMDB propellant with Mg/Al is changed.Meanwhile,the metallic Al fuel combustion efficiency is improved. |
