Design and Analysis of a Flapping-Wing Aircraft with Multi-Degree-of-Freedom Deformable Tail and Wing

To enhance the flight performance of a flapping-wing aircraft and achieve bird-like foldable wing-tail motion, this study designs an ornithopter featuring a deformable wing mechanism and a multi-degree-of-freedom tail mechanism. Through kinematic analysis and calculations, parametric design was conducted for both the deformable wing mechanism and the multi-degree-of-freedom tail mechanism. The motion trajectory and characteristics of the wing mechanism were validated using ADAMS. Subsequently, the simplified 3D model of the prototype was imported into ANSYS Fluent to compute the aerodynamic loads acting on the vehicle. Structural integrity assessment of critical load-bearing components was performed via strength analysis in ANSYS Workbench. This research provides a theoretical foundation and technical support for the design and development of ornithopters.
