A Study on The Aerodynamic Behaviors Learned from Microscopy Imaging of
Beetle Corrugated Hindwing
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.
