金属水反应水冲压发动机系统性能估算

System capability estimating for a metal/waterreaction fuel ramjet system

使用金属 水反应燃料是推进水下超高速航行器的最佳途径,分析了单次注水和二次注水的铝 水反应燃料水冲压发动机系统,得出了燃料质量配比、燃烧室温度、燃烧室压强、系统有效推力、效率等关键技术性能指标。指出了二次注水系统的优越性并提出了一种二次注水系统的实施方案。分析结论与实际系统性能指标相吻合,证明了分析的正确性,可以为系统研究提供参考。

Using metal/water reaction fuel is the best choice for boosting an underwater high speed vehicle. A single water injection and a dual water injection aluminum/water reaction fuel ramjet system were analyzed. The key technical capability parameters, such as mass proportion of propellant, temperature of combustion chamber, pressure of combustion chamber, effective propulsion force of system and system efficiency were obtained. The advantage of the dual water injection system was proved. An actualization scheme was put forward.
