摘要：
The driving structure of a bionic flapping-wing aircraft is designed, and a space rocker-type driving mechanism and a wing torsion mechanism are proposed to realize the 0-shaped spatial trajectory in the process of wing flapping. For the spatial "0" movement of the wing, a pneumatic analysis model of the bionic aircraft is established. The dynamic mesh and the unsteady value calculation method are used to analyze the lift-resistance characteristics at different phases during the flapping process. The aerodynamic efficiency under different parameters is obtained by comparing the air dynamic efficiency and the flow field, which provides a reference for the design of the bionic flapping-wing aircraft and the selection of the flutter mode. The rationality of the structure design is verified by the aerodynamic measurement experiment, bench attitude calibration and outfield flight test. © 2020, Science Press. All right reserved.
