In order to study the characteristics of a new hinge-type adjustable distortion generator and realize the purpose of guiding the adjustment of this type of distortion generator for specific target map, wind tunnel test was conducted to analyze its distortion flow field, and the GA-BPANN was used for modeling, finally a prediction model that can predict the downstream steady-state total pressure distortion map through the Mach number of the incoming flow and the angle of the distortion generator hinge was obtained; based on this model, a rapid design program was designed. The results showed that the prediction model can quickly and effectively predict the total pressure recovery coefficient of each measuring point at the downstream measurement section of the distortion generator, and the rapid design program can effectively simplify the use process of this type of distortion generator.
