Abstract:
Results of experimental investigations in a flow-type annular cylindrical combustor with an outer diameter of 503 mm are reported. The influence of air addition to products of continuous spin detonation of $\mathrm{CH}_4/m\mathrm{H}_2$–air mixtures on the parameters of detonation waves, pressure in the combustor, and specific impulse is considered. It is demonstrated that addition of air to detonation products increases the velocity of continuous spin detonation, the pressure in the combustor, and the thrust, whereas the specific flow rate of the fuel decreases.
Keywords:
addition of air, continuous spin detonation, continuous multifront detonation, methane, hydrogen, air, transverse detonation waves, annular combustor, flow structure, specific impulse.
