Reynolds-averaged Navier-Stokes Equations are solved through CFD technique. Rigid-moving mesh and morphing mesh are adopted to treat rigid motion and structural deformation respectively. Flight dynamics equations are solved coupled with aeroelastic equations. Comparison results show that longitudinal and course characteristic is affected, and the oscillatory cycle is increased because elastic deformation moves aerodynamic center forward and weaken stability margin.
