“…The three-dimensional effect of flow is weakened with increasing aspect ratio, which increases the aerodynamic coefficient [ 47 ]. Based on beetle hind wing models with different geometries, the average lift force was found to increase with increasing aspect ratio in a certain range [ 12 ]. Compared with the other two beetles, P. brevitarsis had a larger range of variation.…”

When beetles are not in flight, their hind wings are folded and hidden under the elytra to reduce their size. This provided inspiration for the design of flapping-wing micro aerial vehicles (FWMAVs). In this paper, microstructures and nanomechanical properties of three beetle species with different wing folding ratios living in different environments were investigated. Factors affecting their flight performance, that is, wind speed, folding ratio, aspect ratio, and flapping frequency, were examined using a wind tunnel. It was found that the wing folding ratio correlated with the lift force of the beetles. Wind speed, folding ratio, aspect ratio, and flapping frequency had a combined effect on the flight performance of the beetles. The results will be helpful to design new deployable FWMAVs.

“…Moreover, this hollow tubular structure of wing veins has a high moment of inertia and can achieve lightweight wings, which can greatly improve the fracture toughness of wing tearing (Sample et al, 2015). With the improvement of experimental conditions, the exploration of the morphology and flapping kinematics of insect wings has made significant contributions to the improvement of wing structure, optimization of control systems, and lightweight design of deceleration mechanisms in flapping MAVs in recent years (Au et al, 2022; Badrya et al, 2017; Karásek et al, 2018; Li et al, 2022; Li et al, 2023; Liu et al, 2021; Liu et al, 2022; Lu et al, 2018; Phan et al, 2016; Phan & Park, 2020; Takahashi et al, 2018; Truong et al, 2019; Zhao et al, 2018).…”

“…Moreover, the hind wings of beetles can fold into wing package with a high folding rate and be covered by the sclerotized elytra. The unique folding mechanism of beetle wings provides a biomimetic new concept for the design of deformable wing MAVs, which can be easily found in some typical flapping wing MAV prototypes (Li et al, 2021; Liu et al, 2021; Phan et al, 2019; Phan & Park, 2020).…”

The folding/unfolding mechanism and collision recovery effect of the beetle's hind wings can provide biomimetic inspiration for the optimization of wing deplorability and the investigation of collision prevention recovery mechanism of new amphibious morphing vehicle. In this study, a method is described to investigate the structural response and mechanical properties of the hind wings of the beetle Protetia brevitarsis under natural conditions. The specially processed test samples were conducted to tensile testing, which facilitates the evaluation of the mechanical properties of specific areas of the hind wing. The micro geometric morphological characteristics of the cross‐section of the specimen after tensile fracture were observed by scanning electron microscopy. The three‐dimensional morphology of the ventral and dorsal sides of the hind wing was characterized using three‐dimensional scanning and reverse modeling methods. The finite element model of the hind wing is developed to investigate the structural deformation and modal response characteristics of its flapping. The uniformly distributed load on the hind wing surface is derived from the lift characteristics obtained from the computational fluid dynamics simulation of flapping wing motion.Research Highlights Scanning electron microscope is used to observe the cross‐sectional characteristics of the veins and membranes. The material properties of the wing membranes and veins of the hind wings were measured using the tensile testing system. The three‐dimensional morphology of the hind wing was characterized using 3D scanning and reverse modeling methods. The finite element model of the hind wing is developed to investigate the structural deformation and modal response characteristics of its flapping.
