| 内容記述 | The experimental studies were conducted to make clear the initiating and driving mechanism of the longitudinal high frequency combustion oscillation in a rocket motor burning a premixed gas as the propellant. The effects of several variables upon the critical oscillation period, which has been found in the previous studies to govern the occurrence of the oscillation, were studied in the beginning. Then the distribution of the gas temperature in the reaction zone during the oscillation was measured in detail. Finally, the photographic study of the reaction zone during the oscillation as well as during the steady combustion was made by the high speed schlieren motion picture. The results have made clear that the shock wave theory in which the driving mechanism depends on chemical kinetic factors is invalid for describing the occurrence of the oscillation. The interaction between the pressure wave and the combustion process which provides the driving force of the oscillation was found to be of a rather complicated fluid-mechanical nature. The shock wave plays no important role in this interaction. The characteristic time which governs the occurrence of the oscillation was identified with the ignition time delay of the unburnt propellant in the hot combustion gas stream. The latter was found to be of a chemical nature depending chiefly upon the propellant equivalence ratio, although some small effects of the combustion chamber pressure and the injection Mach number of the propellant were found in the experiments. | |||||||
