【 摘 要 】

In this paper, the beetle rear wing is used as a bionic object to study the aerodynamic characteristics of the flapping wing aircraft during flapping. Firstly, a three-dimensional folding wing three-dimensional model was designed according to the folding mechanism of the beetle wing. Then the influence of different flapping angle of attack, torsion time and crease width on the aerodynamic characteristics of the rigid folding wing was analyzed by ANSYS FLUENT software. The results show that the flapping angle of attack has a great influence on the aerodynamic characteristics of the foldable wing. Appropriate reduction of the torsion time and crease width can improve the aerodynamic characteristics of the folded wing.
