| Abstract: | In order to analyze the effect of inlet distortion on the aeroengine stability and performance, a numerical calculation method was developed by the two-dimensional unsteady Euler equation with source item. The effect of total pressure distortion on an aeroengine stability and performance parameters was analyzed by the model. The effect of typical influence factor on the critical total pressure exponent was studied. The results show that the accuracy of the model is well and value of engineering application. |
