This paper utilizes high-speed Photogrammetry to investigate the dynamic deformation measurement method of the flexible flapping wing. By coupling the DIC-measured deformation with the CFD method, a CFD approach that considers flexible deformation is established. Comparative results show that wing flexibility reduces lift but markedly increases thrust, underscoring its critical aerodynamic role.
