In order to obtain the influences of different impingement aperture (IA), impingement spacing of flow direction of impingement hole (IFD), spacing of span direction of impingement hole (ISD) coupling effect on impingement cooling characteristics and structural thermal stress of concave wall in reverse flow combustor, CFD calculation and FEA analysis were carried out. Opt LHD in DOE was selected to determine the sample points in the design space, and a high-precision RBFNN was constructed. Based on NSGA-Ⅱalgorithm, multi-objective optimization was carried out for comprehensive cooling efficiency, non-uniform coefficient of wall temperature distribution and maximum wall thermal stress. The results showed that comprehensive cooling efficiency, non-uniform coefficient of wall temperature distribution and maximum wall thermal stress decreased with the increase of ratio of IFD to ISD, ratio of IFD to IA and ratio of ISD to IA. Through multi-objective NSGA-Ⅱ algorithm, the value range of the three objective functions of the Pareto front of concave wall impingement cooling structure was obtained, i.e.: maximum wall thermal stress was not greater than 5 MPa, comprehensive cooling efficiency was not less than 0.66, and non-uniform coefficient of wall temperature distribution was not greater than 0.16. According to the combination of the optimal structure of concave wall impingement cooling: IA was equal to 0.94 mm, IFD was equal to 4.04 mm, and ISD was equal to 5.45 mm.
