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.

The generation of higher lift forces with lower drag is further achieved by increasing the aspect ratio and through the addition of a winglet [2]. Winglet is a small nearly vertical lifting surface that is typically attached to the tip of a wing.…”

In recent years, with the gradual development of the aviation industry, how to make supersonic aircraft truly used in military air defense has become a global problem. In this paper, the wing design of supersonic aircraft is studied, a swept back symmetrical wing suitable for supersonic reconnaissance aircraft is designed with reasonable aspect ratio, span length, sweep angle, thrust weight ratio and wing load. On the basis of the aerodynamic characteristics of the aircraft analyzed, the inboard electron, outboard electron, flasheron, leading edge flap and all moving tip are designed to ensure the controllability in the flight line and to maintain the balance and stability of the aircraft. The qualitative analysis of the flight performance of the wing is also performed. This paper provides a possibility for the design of supersonic aircraft in the future.

In this paper, a multi-agent cooperative control algorithm based on event-triggered mechanism is designed. The main research contents are as follows : Firstly, the consensus algorithm of second-order discrete multi-agent is designed, and the consensus protocol is designed by using sampling position information. The relationship among network topology, control gain and sampling period is analyzed. Secondly, the leader-follower consistency based on event-triggered mechanism is studied, and a leader-follower consistency algorithm based on event-triggered mechanism is designed. By introducing the event-triggered mechanism, the master-slave consistency cooperative control is realized. Thirdly, the research results of multi-agent cooperative control algorithm based on event-triggered mechanism are verified by an example to prove the effectiveness of theoretical analysis.
