Over hundreds of millions of years of natural selection, hummingbirds have evolved excellent flight characteristics. This ingenious wing structure provides a new inspiration for the design of bionic flapping wings. In this paper, a kind of bionic flexible flapping wing is designed with a hummingbird as the prototype, its parametric aerodynamic characteristics are analyzed, and its feasibility is verified by simulation. Combined with the simulation results, the aerodynamic parameters such as lift, drag, and lift-drag ratio are comprehensively considered, and the optimal parameter combination is 5 m/s-20 Hz. Under this parameter combination, the aerodynamic performance is the best, and the lift-drag ratio is as high as 13.3. This paper can provide a theoretical basis and technical reference for further development of bionic flapping wing MAV design.

“…Some studies have explored the impact of wing flexibility on lift and energy requirements by modeling the intricate fluid-structure interaction between the wing and the surrounding air. This approach has enabled researchers to uncover the contribution of both flexibility and inertia to FWMAV performance [15][16][17]. However, to effectively increase the hovering time, finding the best balance between these factors is still an important task from the perspective of developing a FWMAV but remains a largely trialand-error challenge due to the lack of valid design principles [8].…”

“…The effects of the design parameters on the wing performance can be predicted quickly, which allows for combining it with the surrogate optimization method [24] to advance the design of the wing. Using a quasi-steady model instead of the more computationally costly method, such as the direct numerical simulation [15,25,26], allows us to perform optimization programs and detailed sensitivity analysis.…”

Due to the complexity of tailoring the wing flexibility and selecting favorable kinematics, the design of flapping wings is a considerably challenging problem. Therefore, there is an urgent need to investigate methods that can be used to design wings with high energy efficiency. In this study, an optimization model was developed to improve energy efficiency by optimizing wing geometric and kinematic parameters. Then, surrogate optimization was used to solve the design optimization model. Finally, the optimal design parameters and the associated sensitivity were provided. The optimized flapping wing, inspired by hummingbirds, features large geometrical parameters, a moderate amplitude of the flapping angle, and low frequency. With the spanwise twisting deformation considered in the parameterization model, the optimization solver gave an optimized wing with a pitching amplitude of approximately 39 deg at the root and 76 deg at the tip. According to the sensitivity analysis, the length of the wing, flapping frequency, and flapping amplitude are the three critical parameters that determine both force generation and power consumption. The amplitude of the pitching motion at the wing root contributes to lowering power consumption. These results provide some guidance for the optimal design of flapping wings.
