The present paper discusses the design of a pulse-jet engine in which a new mechanism of deflagration-to-detonation transition and establishment of a mode close to the detonation combustion or quasi-detonation mode is realized. It is found that the possibility of such a transition is provided by a special design of the gas duct which has a double bend leading to the formation of a specific vortex structure of the internal flow allowing the acoustic tuning of the gas duct to reach such combustion modes.
