Based on hydrogen-powered ultra-long endurance unmanned aerial vehicle (UAV), nonlinear static aeroelastic characteristics were analyzed by the strong-coupled method for its high-aspect-ratio light composite wing. The aerodynamic comparison of rigid and elastic (aeroelastic deformation) wing was investigated. And then, an aerodynamic correction method, based on the result of the rigid wing, was applied to the elastic wing. The results show that the lift-drag ratio of the elastic wing reduces by 3.2% (compared to the rigid wing), and roll and yaw moments significantly increases to the disadvantage of aerodynamic performance. The aerodynamic correction based on rigid computation results is an efficient aerodynamic analysis strategy for high-aspect-ratio light composite wing.
