In order to study the influences of cavity parameters on the coupled flame response characteristics of bluff body/cavity in aero-engine afterburner, the model afterburner was taken as the research object, and the coupled flame heat release response characteristics under different cavity length-to-depth ratios and rear wall inclination angles were experimentally studied. The experiment was carried out under normal temperature and pressure conditions, and the flame transfer function (FTF) was established. Based on the dynamic flame image, the response characteristics and dynamic characteristics of the coupled flame under different cavity parameters were studied. The experimental results showed that with the increase of the length-to-depth ratio and the decrease of the rear wall angle, the FTF gain and delay time decreased, and the time delay effect of the system was weakened. In addition, under low frequency disturbance, the coupled flame produced inward curling motion characteristics, and multiple flame surface folds could be generated at higher frequencies, resulting in local flameout. In addition, the change of the cavity parameters may change the distribution of the strong heat release pulsation area in the space, which is also the internal cause of the change of the coupling flame response characteristics.
