HAN基液体发射药液滴燃烧特性研究

A STUDY OF THE COMBUSTION CHARACTERISTICS OF A DROPLET OF HAN-BASED LIQUID PROPELLANT

研究LP1846单滴在1－35atm，（440～850） ℃ 环境下蒸发，分解和燃烧的特性。给出液滴从受热到燃尽全过程的时间序列照片。定量测试液滴燃烧的特性参数，实验结果表明，随着压力和温度的提高，液滴的着火延迟期、生存期缩短，微爆特征显著。最后定性分析了一些实验现象。

The characteristics of gasification,pyrolysis and combustion of a single droplet of LP1846 under the ambient condition of l-35atm,440℃-850 ℃ have been in-vestigated.Time series photographs of the droplet from its heating to the end of the combustion process are given.The characteristic parameters of drop combustion have a-lso been measured quantitatively.The experimental results show that with increasing pressure and temperature,the ignition delay time and lifetime of the droplet decrease,marked microexplosion characteristics were observed.Some experimental phenomena are analyzed qualitatively.
