作为固体火箭推进剂主要能量来源，铝粉的结构、形貌对其能量和燃烧性能具有显著影响，采用纳米铝比传统微米铝具有更高燃速、高比冲和低特征信号。Aluminum powder, as a type of metallic fuels in the solid rocket propellants, its structure and morphology has significant effect on energy and combustion performance. The addition of nano aluminum has a higher burning rate, higher specific impulse and lower signal characteristics than traditional micron aluminum（我自己翻译的，润色）. 当前研究的纳米铝多侧重于球形，少见针对非球形各向异性纳米铝的结构调控及其热释放性能研究（这句不晓得如何翻译地道）
Aluminum powder, as a key fuel component of the solid rocket propellants, its structure and morphology has a significant impact on its energy output and combustible performance. Nanoaluminum, in comparison with traditional micro-sized aluminum, has a higher combustion rate, higher specific impulse and lower signal characteristics. Currently, most researches in this field are on nanoaluminum with spherical shape, there has been relatively few studies on non-spherical, anisotropic nanoaluminum with regard to the regulation of the nano structure and its heat releasing properties. |
