Optimization design and analysis of the flapping-wing robotic aircraft

The flapping-wing robotic aircraft achieve the purpose of flight by imitating the flapping of bird wings in nature, which has wide application prospect. According to the bionics principle, this paper designs a small flapping-wing robotic aircraft with high flexibility, and it is driven by three motors. The wing flapping and empennage torsion are realized by gear transmission, four-link mechanism, balance and steering mechanism respectively; the minimum transmission angle of space four-link mechanism is adopted to optimize the target from the design requirements of small flapping-wing robotic aircraft. The optimization design of flapping-wing robotic aircraft is carried out to achieve the minimum transmission angle of four-link mechanism based on NSGA-II, which makes the movement of flapping-wing robotic aircraft more efficient and stable. Finally, the change rule of flapping motion is obtained based on the kinematics simulation of ADAMS, and the feasibility of the scheme is verified.
