A supersonic combustion organizer that consists of both cavity flameholder and strut injector was applied in a liquid-kerosene-fueled model scramjet. The experimental results indicated that the strut injection can improve the combustion performance. When the strut was mounted near the cavity, transverse injection from the strut gave the best performance. However, the excessive long distance between the upstream strut and the cavity led to upstream spreading of combustion to the isolator and pressure rise at the isolator entrance. Besides that, parallel injection was found difficult to establish effective combustion due to the poor spreading performance, except in the condition that the strut was mounted close to the cavity and wall injection was used simultaneously.
