二硝酰胺铵液滴微爆特性的试验研究
Experimental Study on Micro-explosion Characteristics of Ammonium Dinitramide Droplets
绿色无毒航天推进剂二硝酰胺铵(ADN)在燃烧室内会发生微爆效应，从而使得发动机具有较好的燃烧效率和较低的排放污染物。本文以ADN液滴为研究对象，搭建了挂滴式试验系统，给出了ADN液滴在微爆过程中的形态变化及微爆特性表征参数；在此基础上，开展了环境温度和液滴初始直径对液滴微爆特性的影响规律研究。研究结果表明，ADN液滴微爆延迟时间不会随环境温度的增加而缩短；液滴微爆强度和液滴微爆持续时间均会随着环境温度的不断升高而逐渐减小；液滴微爆持续时间所占液滴…查看全部>>
The green non-toxic space propellant ammonium dinitramide (ADN) will undergo a micro-explosion effect in the combustion chamber, resulting in better combustion efficiency and lower emissions for the engine. This article takes ADN droplets as the research object, establishes a hanging drop experimental system, and provides the morphological changes and micro-explosion characteristic characterization parameters of ADN droplets during the micro-explosion proces…查看全部>>
