Three different kinds of mixed air gaps and two different kinds of cavity structures were designed to study the lean ignition performance of trapped vortex cavity afterburner. The experimental researches with different cavities and flow parameters were carried out. The investigation was performed with the mainstream Mach number ranging from 0.17 to 0.3, the pressure ratio of secondary flow to mainstream flow ranging from 0.97 to 1.08. The ignition Mach number, fuel air ratio and predictive model of the trapped vortex cavity afterburner were obtained. The results showed that the fuel air ratio increased with the increasing mainstream Mach number and the pressure ratio of secondary flow to mainstream flow. The bigger cavity with smaller mixed air gap was better for ignition. A predictive model was developed for the fuel air ratio. The error between the predicted value and the experimental value was not greater than 20%.
