旋转爆震发动机（RDE）是一种新型的爆震发动机系统，与脉冲爆震发动机（PDE）等传统发动机相比，具有结构简单、体积小、性能高等优点。然而，目前对RDE的研究还处于起步阶段。通过数值分析，从旋转爆轰的特点和传播极限两个方面来了解旋转爆轰。爆轰下限为2.6MPa，爆轰上限为7.1MPa。发动机性能分析表明，最大混合比冲（Ispm）约为440 s，与目前典型的火箭发动机相当。
The rotating detonation engine (RDE) is a new engine system using detonation, which may provide a higher performance and smaller and simpler design in comparison with the pulse detonation engine (PDE) and other traditional engines. However the research on RDE stands just at the first step now. The authors perform a numerical analysis to understand about RDE in terms of features of rotating detonation and its propagation limit. The lower threshold pressure of detonation limit was 2.6 MPa and the upper threshold pressure of detonation limit was 7.1 MPa. The engine performance analysis shows that the maximum mixture based specific impulse (I spm ) was about 440 s, which is comparable with that of the present typical rocket engine.
