“…The use of jet fuels, for example aviation kerosene, in detonation-based engines is emerging as a promising possibility for the field of aviation [33]. Promoting the development of kerosene-fuel rotating detonation research, especially the research on engineeringlevel, large-scale rotating detonation combustion chambers, is useful for promoting RDE engineering applications.…”

A series of experimental tests were carried out in order to study the propagation characteristics of a liquid kerosene rotating detonation engine (RDE) with different diameters. Distinguished characteristics of spatial and temporal instability were found in the large-scale RDE due to the uneven circumferential distribution of kerosene supply pressure. As for the two counter-waves detonation system, the 500 mm-diameter RDE maintains a higher detonation wave velocity due to its longer injection recovery time. However, the 220 mm-diameter RDE can obtain a larger equivalence ratio operation range, higher specific thrust, and higher specific impulse. In addition, compared with the deflagration combustion, the detonation combustion has higher chamber pressure and thrust under the same operational conditions.
