Abstract: In two-dimensional unstationary state the model of continuously rotating detonation wave in a flow annular chamber with increasing width was formulated in the ejection regime. The model was completed by setting an Abramovich equations for ejector at the entrance of the chamber. The analysis of critical parameters of ejector for hydrogen-oxygen mixtures was done. The dynamic of detonation wave in the chamber and it's structure were numerically analyzed. The minimal period for the total pressure brought from the experiments was found. The comparison with the experimental data was done.

Keywords: oxidizer ejection, continuous spinning detonation, transversal detonation waves, flow structure, mathematical modeling.
