纳米镍粉对Al-CMDB和CL-20-CMDB推进剂燃烧性能的影响
Effect of Nano-Nickel Powder on Combustion Properties of Al-CMDB and CL-20-CMDB Propellants
摘要
Abstract
To investigate the effect of nano-nickel powder with particle size of 50nm on the combustion properties of Al-CMDB and CL-20-CMDB propellants, the propellant samples were prepared through the rolling-absorption method. The burning rates of the propellants were measured by the target line method and the pressure exponents were calculated. The reason of how nano-nickel powder affect the combustion properties of Al-CMDB propellant was studied by flame photo, burning wave, DSC, morphology and elemental analysis of flameout surface. The results show that in Al-CMDB propellant, adding nano-nickel powder can greatly improve the burning rate and reduce the pressure exponent of the propellant. The burning rate of the propellant at 10MPa reaches 35.59mm/s, the pressure exponent between 8-20MPa reduces from 0.43 to 0.17, and the propellant appears mesa effect between 15-20MPa when adding 0.7% (mass fraction)nano-nickel powder into the Al-CMDB propellant. In CL-20-CMDB, adding 0.5%(mass fraction)nano-nickel powder to CL-20-CMDB propellant can increase the burning rate of the propellant greatly at 4-10MPa,the pressure exponent between 8-20MPa is about 0.01 and the propellant appears mesa effect between 15-20MPa.关键词
