Review on the Recent Development of Multi-mode Combined Detonation Engine
首发时间:2012-03-09
Abstract: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.

多模态爆震组合发动机近期发展综述
摘要:近年来,各国都已经将发展高超音速飞行器作为该国国防战略发展的重点,因此研究与高超音速飞行器匹配较好的动力装置也显得尤为重要。现有的推进装置中还没有一款可以独立工作于马赫数0-25和距地面0-100km的飞行空间内。多模态爆震组合发动机是本世纪初提出的一种新概念的动力装置,它由四种相对独立的模态组成并可以独立工作于宽广的马赫数范围和飞行空间,可应用于各种超音速飞行器和巡航导弹上。本文就近期各国在多模态爆震组合发动机的研究上取得的进展做一些总结,分析各工作模态的优缺点以及现阶段发现所存在的问题和未来发展所需要注意的问题。
