The research object of this paper is the static aeroelastic load correction method of civil aircraft. On the basis of fully considering the design characteristics and load correction requirements of modern civil aircraft with high aspect ratio, the existing static aeroelastic load correction method based on the aerodynamic theory of engineering beams and strips is supplemented and improved, and a complete design flow and calculation method is established. The method is verified by the wind tunnel test data. Numerical examples show that the method is efficient and accurate, and has high engineering application value.
