JAXA has been developing the Pre-Cooled turbojet engine with afterburner for hypersonic aircraft. The afterburner will work on super/hypersonic speed to increase the thrust. However, its combustion efficiency is not enough for practical use. To improve the performance of the afterburner, it is necessary to clarify the details of the flow field. Therefore we designed the wind tunnel that can simulate the flow field inside of the afterburner and carried out the PIV measurements, the hot-wire measurements and the flow visualization by Schlieren optical system. The results showed that there was Karman vortex sheet behind the flame-holding strut and its large coherent structures were still kept toward the downstream of the flow.
