摘要:

在改进的氮气充压多功能燃烧器中 ,应用数字高速运动分析及计算机处理技术 ,对系列Al Mg富燃推进剂的低压燃烧特性进行了实验研究。总结并讨论了此类推进剂在低于 3MPa贫氧环境下的点火特性、燃烧过程 ,以及燃速特性与主要成份及燃速催化剂的关系。观测一次燃烧的点火过程、燃面和火焰形貌 ,以及结渣情况。初步分析了结渣成份、成因及影响因素

Abstract:

The combustion behavior of Aluminium Magnesium based solid fuel rich propellants was investigated using modified strand burner and high speed motion analysis system Ignition property,burning process and the relationship between burning rate,main ingredients and catalyzers were discussed under the oxygen poor condition of the pressure less than 3 MPa Preliminary combustion process,appearance of burning and flame,and sediment were observed The ingredients and cause of sediment were analyzed,as well as the influence factors
