燃烧铝滴的聚集状态和直径的测量

Aggregate State and Diameter Measurement of Burning Aluminium Droplets

应用近距摄影和显微密度分析,研究含铝复合推进剂燃烧时铝的聚集状态,在此基础上,提出燃烧铝滴直径的测量方法,并用它考察了配方中AP和铝的粒度与燃烧铝滴直径分布间的关系。

The macrophotography and density measurement have been employed in the research of the combustion of aluminized composite propellants in order to obtain the information of the aggregate state of burning aluminium droplets. A method for measuring the dia- eters of burning aluminium droplets is then suggested. The method has been applied to investigate relationship between the diameter distribution of burning aluminium droplets and the original sizes of both AP and aluminium grains.
