“…In fact, since there is no need to temporarily contain the reactants in a detonation chamber, the CDE appears to be eminently suited for launch vehicles. 16,[45][46][47] The brief review above shows that the novelty of RDEs introduces some unique challenges, ranging from an understanding of the basic physics of the detonation and blast wave propagation in a narrow channel through integrating them into a propulsion system, despite an earlier phase of development 50 years ago. Due to the relative paucity of research in RDEs, the focus of this paper is primarily to consider what efforts are required to bring RDEs into reality, ranging from fundamental scientific investigations to systems studies.…”

Rotating detonation engines (RDEs), also known as continuous detonation engines, have gained much worldwide interest lately. Such engines have huge potential benefits arising from their simplicity of design and manufacture, lack of moving parts, high thermodynamic efficiency and high rate of energy conversion that may be even more superior than pulse detonation engines, themselves the subject of great interest. However, due to the novelty of the concept, substantial work remains to demonstrate feasibility and bring the RDE to reality. An assessment of the challenges, ranging from understanding basic physics through utilizing rotating detonations in aerospace platforms, is provided.

This paper presented a three-dimensional numerical study of rotating detonation engines, exploring the effect of the inlet total pressure and the number of detonation waves on the performance of rotating detonation engines. It was found that under the same total pressure of the inlet fuel, the number of detonation waves had little influence on the specific impulse, the thrust and the outlet flow of RDE. The number of detonation waves, however, affected the time needed to reach stable detonation. Besides, there was instability phenomenon in the development of detonation waves due to the relation between the number of detonation waves and the inlet total pressure. In order to speed up the process from ignition to stable detonation, the total pressure of the inlet fuel should match with the ignitions.
