In recent years, extensive experiments of CRDE have been carried out in the Institute of Hydrodynamics by Bykovskii et al.11, 12 and 13 in Russia. They achieved continuous liquid and gas fuel detonations of multi-cycle in combustors of different shapes under different injection systems. The basic geometric configurations are shown in Fig. 511. The tested fuel included acetylene, hydrogen, propane, methane, kerosene, gasoline, benzene, alcohol, acetone and diesel. The oxidant was air or gaseous oxygen and in some cases, liquid oxygen. Without tail nozzle, the specific impulse of CRDE using kerosene-oxygen mixtures in experiments was as high as 200 s. In addition, the compensation technique was used to capture the flow filed inside the CRDE combustion chamber. The results of stable rotating detonation waves are shown in Fig. 611 (1-fuel and oxidizer injection, 2-annular duct, 3-mixture, 4-detonation wave, 5-products, 6-contavt discontinuity, 7-oblique shock wave, 8-product backflow, D-direction of the detonation propagation).

Ну ладно это теория, а ниже:

With the increasing international cooperation, more and more researchers are involved in the experimental studies of CRDE. Extensive CRDE experiments have been carried out by Wolanski’s group14 in Poland. Different geometries of cylindrical chambers, ranging from 50 mm to 200 mm in diameter, were tested with fuels of acetylene, hydrogen, methane, ethane, propane and kerosene with air, oxygen-enriched air, and oxygen under different injection stagnation pressures and back pressures. Long durations of stable detonation waves were obtained. The experimental devices and obtained pressure signals of CRDE are shown in Fig. 7 and Fig. 8.14
