Abstract

The study focuses on the condition for appearance of detonation/quasi-detonation combustion in the ejector pulsejet engine. An interpretation of the spherical detonation initiation mechanism is suggested. The spectra of acoustic pulsations accompanying the transition to detonation or quasi-detonation combustion during changes in the gas duct geometry were measured.
