Mg粉/CO2点火燃烧性能实验研究

Experimental study on ignition and combustion performance of Mg/CO_2

利用自行设计的点火实验装置对Mg粉/CO2的点火燃烧性能开展了实验研究。通过记录的实验现象验证了Mg粉/CO2组合作为推进剂的可行性的同时,由测量到的不同粒径的Mg粉在CO2中的点火温度,对点火燃烧性能作出详细的分析和评估,得到了中等粒径的Mg粒子在CO2中的点火温度约为960 K,且随着粒径的增大,点火温度会逐渐升高,为粉末火箭发动机的设计提供了参考。

The ignition performance of Mg and CO2 was studied by a self-designed experimental device.The ignition phenomena of the reaction Mg and CO2 was clearly exhibited by kinescope,which provided the checkout of temperature curve and also validated the combustion mode of the Mg and CO2.The ignition temperature of reaction of Mg and CO2 was confirmed,middling scale Mg was ignited at 960 K and the change law that the temperature is raised as the increase of particle diameter is revealed.
