“…In contrast with Billingsley et al, 34 this method did not lead to a significant thrust penalty. Huang 35 numerically optimized the geometric parameters of an eagle wing in order to maximize lift and thrust forces. Lift and thrust forces of his initial design were 3.85 N and 0.16 N, respectively.…”

Many developments in aerospace science have originated from nature. One of these developments has been obtained through inspirations from flying locomotion. The aim of this study is to simulate the flapping mechanism of the black-headed gull in forward flight. The wing of the black-headed gull is characterized entirely by complex dihedral, dividing the wing into two distinct parts. Hence, a flapping mechanism with different bending deflection angles is constructed and compared with a primitive flapping mechanism. Firstly, parametric studies are conducted to assess the role of flapping frequency, velocity and bending deflection angle on the lift, thrust and power loading of the membrane flexible wing at 10 ° angle of attack. Secondly, dimensional analysis is used to establish the similarity between the real gull and the constructed mechanism. Superiority of the bending deflection mechanism is concluded in forward flight against simple flapping wing in terms of aerodynamic forces as well as power loading parameter. It is found that although the aerodynamic coefficients decrease with increase in advance ratio, the best power loading of the black-headed gull is obtained between advance ratio of 2 and 3, in the gull's aerodynamically quasi-steady regime.

“…An ornithopter is a drone whose wings flutter up and down like birds or insects. Most researches contribute and innovate in the following aspects: wing shape analysis [2,3], the aerodynamics of flapping wing [4][5][6][7], power extraction performance of semiactive flapping airfoils [8], mechanism [9][10][11], different actuation mechanisms, hybrid actuation mechanisms [12], electrical motor-driven method, mechanical transmissiondriven method, and "artificial muscle" material-driven method [13].…”

The current flapping wing adopts T-shaped or cross-shaped tail fin to adjust its flight posture. However, how the tail fin will affect the hover control is not very clear. So, the effects of the two types of tail on flight will be analyzed and compared by actual flight tests in this paper. Firstly, we proposed a new X-wing single-bar biplane flapping-wing mechanism with two pairs of wings. Thereafter, the overall structure, gearbox structure, tail, frame, and control system of the flapping wing were designed and analyzed. Secondly, the control mechanism of hover is analyzed to describe the effect of two-tail fin on posture control. Thirdly, the Beetle was used as the control unit to achieve a controllable flight of flapping wing. The MPU6050 electronic gyroscope was used to monitor the drone’s posture in real time, and the Bluetooth BLE4.0 wireless communication module was used to receive remote control instructions. At last, to verify the flight effect, two actual flapping wings were fabricated and flight experiments were conducted. The experiments show that the cross-shaped tail fin has a better controllable performance than the T-shaped tail fin. The flapping wing has a high lift-to-mass ratio and good maneuverability. The designed control system can achieve the controllable flight of the flapping wing.

“…Meng simulated the movement characteristics of a fly during flight, and the designed aircraft improved the lift during flight (Meng et al, 2017). Ming designed the aircraft based on the bionic eagle wing structure, which improved the flight performance of the aircraft (Huang, 2018). Ge and others extracted the biomap from a wing biological model of an owl, which applied it to aircraft wing design to improve the lift of an aircraft during flight (Ge et al, 2013).…”
