TLDR
In this paper, a liquid-fueled and valveless PDRE without the purge process was proposed, and a maximum operating frequency of 110 Hz was achieved when oxygen-enriched air with 25%∼45% oxygen by volume was employed.About:

Thermal management method of fuel in advanced aeroengines
TL;DR: In this paper, a one dimensional model of flow and heat transfer process in a single cooling channel of an endothermic hydrocarbon fuel cooled scramjet was developed, which was validated by corresponding experimental data, and different methods were put forward to control the utilization level of fuel heat sink and effective residence time of fuel during fuel cooling process.

Hydrogen-air, ethylene-air, and methane-air continuous rotating detonation in the hollow chamber
TL;DR: A series of hydrogen-air, ethylene-air and methane-air continuous rotating detonation (CRD) tests are performed in the hollow chamber with the variations on nozzle contraction ratio and equivalence ratio.

Rotating detonation in a combustor of trapezoidal cross section for the hydrogen–air mixture
TL;DR: In this paper, a combustor of annular trapezoidal cross section is numerically studied for the first time and it is shown that reflected shock waves, explosions and new detonation waves occur near the corners of the combustor, but they do not stop the continuous propagation of the rotating detonation wave.

Operation of a liquid-fueled and valveless pulse detonation rocket engine at high frequency
TL;DR: In this article, a valveless mode with the purge gas based on liquid fuel was developed to increase the operating frequency and enhance the propulsive performance of a pulse detonation rocket engine.

Review of Propulsion Applications of Detonation Waves
TL;DR: In this article, the advantages of the detonation cycle over the constant pressure combustion cycle, typical of conventional propulsion engines, are discussed, and the impact of the early work on these recent developments and some of the outstanding issues are also discussed.
