Abstract : When bodies are fired at high speeds into hydrogen-air and hydrogen-oxygen mixtures we observe several characteristic flow regimes: stationary --with smooth shock and thermal fronts; non-structure of the burning region in the form of circular waves; regimes with complex structure, with formation of internal discontinuties that interact with the forward shock and distort it. Stationary regimes have been studied previously, and the basic results have been described. The report gives an explanation for the occurrence of pulsational burning regimes originating during hypersonic flow past a wedge and the leading edge of blunt bodies.
