| In the next few years, the development of hypersonic aircraft will be the priority of national defense strategy of many countries, and the significance of the propulsion system applied on the aircraft is self-evident. At present, there are no propulsion systems for the aircraft can be used independently in wide range of Mach numbers and flight envelop. The multi-mode combined detonation engine, which consists of four modes, is a novel propulsion concept proposed at the beginning of this century for potential application on hypersonic cruise or space access. The multi-mode combined detonation engine is thought to be a promising propulsion system which can be used independently in wide range of Mach numbers and flight envelop. Recently, many countries extremely valued the development of multi-mode combined detonation engine and much progress is obtained. A review is made to the recent development of the multi-mode combined detonation engine in this study. The superiority and disadvantages are comparatively analyzed and the major progress for each mode is detailed introduced in the following text. Also, the problems need to be attention in the future development for multi-mode combined detonation engine is discussed. |
