摘要
铝基合金燃料作为固体推进剂的核心组分之一,其成熟制备技术与燃烧性能优化是提升火箭动力系统的关键。文章梳理了铝基合金燃料的几种典型制备技术及其优缺点,重点评述了铝基合金燃料的国内外研究现状,系统总结了铝-锂合金(降低点火温度)、铝-镁合金(抑制燃烧团聚)、铝-硼合金(增强燃烧效率)等8类典型合金体系的燃烧调控机理以及稀土元素掺杂与三元合金设计对燃烧效率的协同强化效应。当前铝基合金燃料研发仍面临燃烧反应机理存有争议与规模化生产稳定性不足的双重挑战,需深化组分设计-微观结构-宏观性能的跨尺度关联研究。
As a core component of solid propellants,aluminum-based alloy fuels rely critically on mature preparation technology and optimized combustion performance to enhance rocket propulsion systems.This paper reviews typical preparation techniques for these fuels,comparing their advantages and disadvantages,and assesses current domestic and international research progress.Combustion modulation mechanisms for eight representative alloy systems are summarized,such as aluminum-lithium alloys(reducing ignition temperature),aluminum-magnesium alloys(suppressing combustion agglomeration),and aluminum-boron alloys(enhancing combustion efficiency).Synergistic combustion enhancement through rare earth element doping and ternary alloy design is discussed.Current development still faces dual challenges:controversial combustion reaction mechanisms and insufficient stability in large-scale production.Deepening cross-scale studies linking composition design,microstructure,and macroscopic properties is essential.
