As is generally thought, continuously rotating detonation should keep going around the combustor regularly and has a fixed period. However, from the figures gotten by the data acquisition system, two kinds of breathing phenomena, Low Breathing and Deep Breathing, are discovered in the experiment. Actually they are caused by the changing mass flux, which stems from the pressure change in the combustor. The two kinds of breathing phenomena have different time scales and combustion mechanism. Reverse DDT is also discovered in one of the breathing phenomena. Since RDE is strong in thrust and high in efficiency, it has a great application foreground in the Aerospace Engineering. © 2013 The Authors. Published by Elsevier Ltd.
