Design and analysis of a bionic flapping wing aircraft flying at ultra-low altitude

In order to develop an aircraft with certain load capacity and high concealment, a bionic flapping wing aircraft which can fly at ultra-low altitude was designed according to the flight mode of birds. Firstly, the degree of freedom of the transmission mechanism of flapping wing aircraft was calculated, the feasibility of the design scheme was determined in principle, and the dimensions of each component of flapping wing aircraft were determined. Secondly, the three-dimensional model of the aircraft was drawn by the design software Creo. Through the motion simulation, it was concluded that the flutter of the aircraft met the design requirements. Then, the dynamics simulation of the aircraft was carried out by ADAMS (automatic dynamic analysis of mechanical system) software, and the changes of flapping amplitude and angular velocity in the flapping process were obtained. Therefore, the rationality of the three-dimensional model design of the aircraft was verified, and the balance torque at the rotating joint of the aircraft was calculated. Finally, the prototype of flapping wing aircraft was made, and indoor and outdoor flight tests were carried out. The dynamics simulation analysis and flight tests showed that the designed flapping wing aircraft had good flapping stability, relatively strong flight ability and bionic concealment, and the flight effect reached the expectation. The flapping wing aircraft can fly at ultra-low altitude and has a wide application prospect.
