Study on Unsteady Aerodynamic Characteristics of Bionic Flapping Wing Aircraft

Abstract

This paper studies the aerodynamic characteristics of the composite motion of the wing during the flight of the bionic flapping wing. The dynamic hybrid mesh technique is used to solve the Nave Stokes (N-S) equation, and the changes of the lift resistance generated by the wing under different flapping amplitude, flapping frequency and chord torsion angle parameters are analyzed. By analyzing the aerodynamic efficiency of the wing, the optimal motion parameters of the flapping wing are obtained, which provides a theoretical basis for the design of the flapping bionic aircraft.
