摘　　要：本文首先概述了爆轰现象、爆轰气动物理、爆轰推进概念和爆轰推进研究进展。然后重点介绍了目前正在研究中的主要爆轰推进概念 ,如脉冲爆轰发动机 ,斜爆轰推进 ,冲压加速器。并从热效率和比冲的角度把脉冲爆轰发动机和传统的喷气推进发动机作了比较。Detonation phenomena, detonation physics, detonation propulsion concepts and their research are introduced with a special emphasis on topics of interests, such as pulse detonation engines, oblique detonation wave-based ramjet and scramjet, ram accelerators. And then, comparison of thermodynamic efficiency and specific impulse between the pulse detonation engine and conventional propulsion engines are presented to explain inherent theoretical advantages of detonation over deflagrative combustion. Finally, problems and research topics related to practical development of detonation propulsion are summarized and discussed.
