Journal of System Simulation

Abstract: The aerodynamic characteristics analysis of flapping-wing is of great significance to the design, manufacturing and control of the aircraft. In this paper, a simple motion model of multiple-Degrees-of- Freedom (multi-DOF) of “swing-torsion-bending and folding” is established by analyzing the flight characteristics of bird-like flapping wing. The flapping-wing air vehicle of multi-DOF is numerically simulated in the case of unsteady flow at low Reynolds number by XFlow software. The effects of flapping wing shape, frequency and inflow on surrounding air are analyzed. The simulation results provide theory and technique supports for the flapping-wing air vehicle'research and development.
