摘　　要：本文论述了脉冲爆震发动机的工作原理 ,主要特点 ,应用前景以及国外发展趋势。汇报了本研究小组在脉冲爆震发动机方面所进行的理论 ,试验 ,数值分析研究成果。对 2 1世纪脉冲爆震发动机的研究内容 ,关键技术 ,发展途径进行了探讨。This paper reviews the principles and primary characteristics of Pulse Detonation Engine (PDE), the prospect of its application and trends of its development. The results of our recent theoretical, experimental and numerical researches of pulse detonation engines are summaried. The experiments of a two-phase PDE with three different diameters were carried out successfully. The gasoline/air mixture was used in the PDE. The ignition frequency can vary in the range of 5 [similar to] 117 Hz. The ignition energy of the spark igniter used in these experiments is approximately 50 mJ. The PDE research areas, key technology and development stages in 21 century are foreseen.
