Detonative combustion of hydrogen-air mixture incoming into an axisymmetric convergent-divergent nozzle with the supersonic velocity at low and high altitudes is considered. The investigations are fulfilled on the base of two-dimension Euler gas dynamic equations for multi-component reacting gas. A detailed model of chemical transformations is used. Possibility of stationary detonative combustion of hydrogen in the divergent nozzle part is shown numerically. The obtained regimes of detonative combustion are stable with respect to the periodical concentration perturbations of the inlet hydrogen.
