Abstract: Some results of studying the combustion of hydrogen in a high-velocity air flow at stagnation temperatures below $3000$ K are given. Flame shape and combustion zone length change at temperatures above $2000$–$2200$ K due to deterioration in the fuel–oxidizer mixing process. It has been shown that dissociation processes have an effect on the process of hydrogen combustion at a high temperature. In experiments, they can be detected by a change in the intensity of radiation from the intermediate $\rm OH^*$ radical.
