摘要
本文采用挂滴装置和高速摄影系统研究了 HAN基液体发射药 LP1 846单滴在富含水蒸气高温环境中着火、燃烧的特性。给出了液滴从受热到燃尽全过程的时间序列照片 ,定量测试液滴着火、燃烧的特征参数 ,并分析了环境条件对特征参数的影响。探讨了液滴的微爆机理。建立了液滴着火的简化工程计算模型 ,计算值与实测值吻合较好。研究结果对分析再生式液体发射药火炮内弹道过程有参考价值。
Based on a suspended droplet apparatus and a high speed camera, the ignition and combustion properties of a HAN based liquid propellant LP1846 droplet have been investigated under rich in water vapor hot ambience. Time series photographs of the droplet from start of heating to the fully burned state are given. The characteristic parameters of the droplet are measured quantitatively. The effects of ambience factor on the characteristic patarreters are analysed. Mechanisms of droplet microexplosion are discussed. A simplified engineering calculation model on the ignition of droplet is set up, and the calculated values are found to be in good agreement with the experimental data. The research results are of value to the analysis of interior ballistic process of regenerative liquid propellant guns.
