In the study of bionic flutter vehicles, the fluttering wing is the main source of thrust and lift of the vehicles. However, since the research on low Reynolds numbers related to bionic flutter vehicles is still in its early stage, the research on the aerodynamic characteristics of flutter vehicle is mainly through computational fluid dynamics and wind tunnel tests. Most of the studies on the wing lift characteristics of flutter aircraft through computational fluid dynamics are focused on two-dimensional airfoils and three-dimensional single-degreeof-freedom flutter wings. In this paper, the effect of three different flutter parameters on the aerodynamic performance of the bionic flutter aircraft is analyzed by using the computational fluid dynamics software Fluent to solve the N-S equation. It is shown that the phase difference of flutter, the frequency of flutter, and the amplitude of flutter all have a large effect on the lift coefficient, which provides a theoretical basis for the subsequent research of flutter aircraft.
