Abstract

Beetle hindwings have the unique advantages of lightweight and high strength, which play a key role in flight. In this study, the beetle hindwings were cut along the chordal direction, then the first groove microstructure of different vein cross sections was investigated using the 3D microscope system and LSCM. It was found that the position of the first groove relative to the entire chordal cross-section of the wing gradually moves backwards, which has an effect on the flying aerodynamic behaviors of the beetle. Next, three corrugated airfoils (CA models) learned from the microscopy imaging of ladybird beetle hindwing were designed. Then aerodynamic behaviors were calculated by ANSYS Fluent software, it was confirmed that the position of the first groove microstructure affects the aerodynamic performance of the airfoil. For further study the influence of corrugated structural and motion parameters on the aerodynamic, 2D ‘simplified’ airfoil models with triangular corrugations (TWA models) were developed and studied.
