An experimental investigation of coupling small strut and cavity for enhancing supersonic mixing and combustion had been carried out on direct-connect supersonic combustion test facility. The wall static pressure, CH* chemiluminescence imaging and the schlieren system were used to research the effect of different strut type and jet. For long distance of strut to cavity, when the fuel injection was in a supersonic flow , the effects of combustion enhancement was obvious and was weakened on subsonic mode. For short distance of strut to cavity, combustion enhancement effect is very obvious, significantly increase the volume of high-temperature flame near the cavity.
