摘要:

面向宽空速域的重复使用涡轮基组合动力是世界关注的革命性技术。首先,简述了涡轮基组合动力的发展状况。随后,着重介绍了所提出的面向高超声速民机的多通道双涡轮引射冲压(MUTTER)组合动力的技术特点及研究进展:相较常规涡轮基组合动力系统,MUTTER组合动力采用独特的四通道对称构型,通过亚燃通道中的引射增推桥接双涡轮与冲压的推力鸿沟;规划了分尺度、分阶段的研究与验证方式;针对核心子系统的研究表明,进排气子系统可在宽空速域高效稳定工作,引射亚燃子系统可与其他子系统有效匹配。在此基础上,讨论了本组合动力的飞/发一体化特点。最后,给出了前期工作的若干认识。

Abstract:

The reusable turbine-based combined cycle engine for wide-space/speed range aircraft is a revolutionary technology attracting global attention. Firstly, this paper briefly describes the state-of-the-art of turbine-based combined cycle engines, and then focusing on the technical characteristics and research progress of the presented Multi-ducted Twin-Turbines Ejector-Ramjet/scramjet (MUTTER) combined cycle engine for hypersonic civil aircraft. Different from conventional turbine-based combined cycle engines,MUTTER uses the distinctive symmetrical configuration of four engine ducts. An ejector engine is placed in the ramjet duct to bridge the thrust gap between the twin turbine engines and the ramjet/scramjet engine. A scaled and staged research and verification plan is introduced, and the study on the core sub-systems shows that the inlet and nozzle sub-systems can work stably and efficiently in the wide-space/speed range, and the ejector ramjet engine sub-system can effectively match with other sub-systems. In addition, the aircraft/engine integration features of the present combine cycle engine are discussed. Finally, some conclusions are drawn from our previous work.

Key words: turbine based combined cycle engine, multi-ducts inlet and nozzle, twin-turbines, ejector ramjet, aircraft/engine integration
