The paper describes the results of experimental investigations of a supersonic combustion chamber with solid and discrete cavities at the entrance Mach numbers of 3 and 3.5. Kerosene and propane were used as fuel. The conditions required for self-ignition and intense combustion of the fuels were determined. The possibility of efficient combustion in a supersonic flow was demonstrated. Analysis of applicability of existing criteria predicting the conditions of self-ignition and extinction of combustion has been performed based on the experimental results obtained.
