氟化物对Mg/NaNO3富燃料推进剂燃烧性能的影响

为改善推进剂的燃烧、点火性能，降低燃烧过程中的团聚，应用不同的实验处理方法将不同的氟化物添加入Mg/NaN03富燃料推进剂体系中，在燃烧室内氮气加压下点燃推进剂，收集固体燃烧产物，研究了氟化物对于体系燃烧特性的影响；SEM电镜分析了MglNaN03体系燃烧产物团聚的情况；对比了添加氟化物后体系燃烧产物的颗粒度；分析了不同氟化物的不同影响机理。结果表明，体系外加5%氟化物后，不同程度地降低了体系的燃速，改变了燃烧产物颗粒度分布，氟化镁的生成有利于降低产物的团聚程度。

Influence of Fluorides on Combustion Characteristics of Mg/NaNO_3 Fuel-rich Propellants

Several kinds of fluorides were mixed into Mg/NaNO3 fuel-rich propellants by the different experimental methods for improving combustion and ignition performances,decreasing agglomeration of the metal.Burning rates of the propellants were measured.Solid combustion products of the Mg/NaNO3 composites mixed by fluorides were collected and analyzed by SEM and XPS.And the particle size distributions of solid combustion products were compared among the different formulations;and the effect action mechanisms of t...
