Other AbstractFlexible aircrafts tend to undergo large deformations under aerodynamic forces.As a result, structural geometric nonlinearity occurs.The linear small-deformation theory cannot provide accurate results for analyzing static aeroelasticity.Fluid structure-coupling method based on three-dimensional RANs, Navier-Stokes equations and nonlinear static equation is used for static aeroelastic analysis with structural geometric nonlinearity.The mentioned approach adopts the nonlinear incremental finite-element method to solve nonlinear static equations with assembled structure stiffness matrixes.Moreover, RBF method is used for data interpolation and mesh deformation.Based on the multi-material wing finite-element model, the numerical simulations were made to analyze the static aeroelastic behavior.Comparisons of twist angles, vertical displacements, spanwise displacements and life coefficients between linear and nonlinear structures were made.The results show that geometric nonlinearity cannot be neglected for predicting accurate static aeroelastic behavior for large, flexible airplanes.
