摘　　要：在混流燃烧室内组织富燃燃气与空气的高效稳定掺混燃烧对于空气涡轮火箭发动机(ATR)性能至关重要。回顾了国外各研究机构关于ATR掺混燃烧方案的试验研究,对波瓣混流器在航空领域强化内、外涵气流掺混中的典型应用及研究成果进行总结评述,总结并提出ATR掺混燃烧的特点和关键问题,分析了后续掺混燃烧研究中需重点关注的问题。It is absolutely crucial for the performance of air-turbo-rocket engine in which forms an efficient and steady mixing combustion of air and fuel-rich gas in the combustion chamber. The experimental investigations on schemes of turbulent mixing and combustion for air-turbo-rocket engine, which are proceeded by worldwide institutes, are reviewed. Typical applications and various research achievements of aeronautic lobed mixers for enhancing molecular mixing between bypass and core flows are assessed. An essential summary of characteristics and key problems about turbulent mixing and combustion is carried out. Furthermore, the focuses on turbulent mixing and combustion in subsequent researches which should be paid extra attention are analyzed.
