Design and Coupling Dynamics Research of a Single-drive Multi-mode Flapping-wing Aircraft

Abstract

Aiming at the problems of single flapping wing movement mode and low flight flexibility and stability of flapping-wing aircraft, a single-drive multi-mode flapping-wing aircraft based on the space linkage mechanism is designed. The kinematic model of the flapping-wing aircraft is established, and the driving mechanism is analyzed by Matlab and Adams co-simulation, and the kinematic characteristics of the flapping-wing aircraft is obtained by comparison. The aerodynamic model of a single-drive multi-mode flapping-wing aircraft is established. The windward resistance with periodic variation is applied to the wing, and the dynamic characteristics of the flapping-wing aircraft are analyzed. Through the kinematic and aerodynamic coupling analysis of the combined mechanism, the coupling dynamic characteristics of the flapping-wing aircraft are obtained, which provides a research basis for the flight control and performance improvement of the flapping-wing aircraft in the future.
