“…Another type of bird wing inspired by nature, known as the hummingbird, has also made progress in flapping wing UAVs due to its flapping mechanism and excellent characteristics of high agility and maneuverability, backward motion, long duration hovering, and being able to rotate their wings 180°. Kumar et al [ 47 ] used ANSYS Fluent to perform fluid-structure interaction, where CFD simulation is conducted to study the aerodynamic performance of the wing of a giant hummingbird and compared it with the experimental study. It can be found that the wing was excited at 14 Hz, with negative drag indicated as positive thrust with high Cl .…”

In many modern engineering fields, computational fluid dynamics (CFD) has been adopted as a methodology to solve complex problems. CFD is becoming a key component in developing updated designs and optimization through computational simulations, resulting in lower operating costs and enhanced efficiency. Even though the biomimetics application is complex in adapting nature to inspire new capabilities for exciting future technologies, the recent CFD in biomimetics is more accessible and practicable due to the availability of high-performance hardware and software with advances in computer sciences. Many simulations and experimental results have been used to study the analyses in biomimetics applications, particularly those related to aerospace engineering. There are numerous examples of biomimetic successes that involve making simple copies, such as the use of fins for swimming or the mastery of flying, which became possible only after the principles of aerodynamics were better understood. Therefore, this review discusses the essential methodology of CFD as a reliable tool for researchers in understanding the technology inspired by nature and an outlook for potential development through simulations. CFD plays a major role as decision support prior to undertaking a real commitment to execute any design inspired by nature and providing the direction to develop new capabilities of technologies.

The hind wings of beetles are deployable and play an essential role in flight. In the Asian ladybird Harmonia axyridis (Coleoptera: Coccinellidae), the pterostigma (pst) is found in the middle of the hind wing instead of at the tip of the hind wing. This paper investigates the effect of the pst on the vibrational characteristics during the flight of H. axyridis. Based on cross sections of the pst and veins as well as the morphology and nanomechanical properties of the hind wing, including the wing membrane and veins, three three-dimensional coupling models, Models I-III, of hind wings with/ without pst structures and veins with varying or uniform reduced moduli are established. Modal analysis results for these three models show that the vibrational characteristics and deformation tendencies change the flight performance of the hind wing models with pst structures compared with that of the other models. The results in this paper reveal that the pst structure has an important influence on vibrational characteristics and deformation tendencies and, hence, on flight performance; the relationships between the body mass and the area of the hind wing, which have significant implications for the design of biomimetic deployable wing structures for micro air vehicles (MAVs), are also analyzed. The aim of this paper is to investigate the relationship between the body mass and hind wing area and the function of the pterostigma of the hind wing of a selected beetle species. In insect-inspired flapping-wing micro air vehicles (FW-MAVs), researchers are constantly striving for more lightweight and miniaturized designs 1,2. The multifunctional structures of dragonfly wings have inspired the bionics of micro air vehicles (MAVs) 3,4. MAVs based on birds whose wing span is reduced to 15% with a wing-folding mechanism have also been designed 5. Harmonia axyridis is a lightweight insect whose deployable hind wing can fold to an area reduction ratio of 2 6,7. The folding mechanism of the hind wings of beetles can serve as useful inspiration for the design of deployable wings for MAVs with reduced sizes 5,7. Therefore, for the design of smaller MAVs, research into deployable wings is meaningful. Different wing geometries have distinct kinematics under varying flow conditions 8. The complex, deformable structural shapes and material characteristics of insect wings change continuously during flight, which is powered by flight muscles 9,10. Various angles of attack, wingtip trace patterns, wing areas and complex adjustments to feather orientation can be combined to enable advanced flight capabilities 11-13. In the design of MAV wings, the relationships between wing length, wing area and body weight should be considered 14. To design an MAV that can generate the maximum thrust and lift with the minimum body weight, it is necessary to assess the dependence of the lift and thrust on the wing shape and area 15. With increasing flight speed, the wing-beat amplitude, wing-beat duration, wing-beat frequency, and angle of attack of the wings and ...
