基于连续旋转爆震的推进技术研究进展

基于爆震燃烧的推进技术是未来空间技术的重要发展趋势，特别是可实现结构简单化设计和高热力学效率.针对火箭式连续旋转爆震发动机、吸气式爆震发动机的实验测试和数值仿真，文章综述了其国内外研究进展，分别总结了不同燃料、燃烧室结构、喷注方式以及工作方式等对连续旋转爆震波的传播规律和发动机的特性影响规律.虽然上述探索性研究得到了诸多有益的结论，但是由于连续旋转爆震燃烧技术涉及的流动、物理化学过程十分复杂，对旋转爆震燃烧的机理研究仍然有待进一步深入开展. 

Progress in Research of Rotating Detonation Propulsion

The propulsion technology based on detonation is a major trend for the future development of space technology,especially for its simple structural design and high thermodynamic efficiency.This paper conducted a series of latest researches for rotating detonation rocket engine and air breathing rotating detonation engine,including experimental tests and numerical simulation.It also discussed the propagation property of rotating detonation waves and the effects on engine’s properties in terms of different fuels,combustion chamber structures,injection methods and operating modes.The aforementioned exploration has shown many beneficial results.However,since the flow,the physical and chemical progresses involved in rotating detonation technology are complicated,the mechanism of rotating detonation still needs to be studied in a further step.
