铝水反应机理的试验研究与分析

Experimenrally study of aluminum-water reaction mechanism

铝水反应是铝水推进系统的能量来源。这种能量来源在用于水下推进时,因无需携带水,而具有非常高的体积能量密度。应用铝水推进系统面临的是铝与水反应的启动和反应的持续进行的问题。在铝水反应的起始阶段添加助燃剂可以减少启动时间。采用旋涡燃烧器可以保证铝水反应的持续进行。向燃料中添加粘合剂,制成流态药柱,便于燃料的输送。本文对铝与水的反应进行了试验,考察了燃料中铝粉粒度、粘合剂和铝水反应起始阶段助燃剂对铝水反应的影响,初步研究与分析了其反应机理,并提出了下一步研究的思路。
