Aircraft engine air system probability analysis method based on Kriging model

The invention belongs to the technical field of aircraft engine air system analysis, and particularly relates to an aircraft engine air system probability analysis method based on a Kriging model, which comprises the following steps of: carrying out statistical analysis on input variable statistical data of an air system, and carrying out Latin hypercube sampling; carrying out Sobol sequence sampling in an air system input variable design space; performing air system analysis solution on an input variable sample sampled by the Sobol sequence to obtain a corresponding air system response value; establishing a Kriging model by using an input variable sample sampled by the Sobol sequence and a corresponding air system response value; solving an input variable sample of Latin hypercube sampling based on a Kriging model to obtain a corresponding air system prediction value and a prediction error; and analyzing the air system based on the air system prediction value and the prediction error. 本申请属于飞机发动机空气系统分析技术领域，具体
