N2 - Flapping-wing propulsion is a form of propulsion that is widely found in nature. Based on biomimicry, it has been found that double-wing flapping propulsion has the characteristics of high efficiency, easy mechanical design, and stable lift and inertial forces, while jellyfish-based MAVs have good hovering stability. This paper investigates the flow field, aerodynamic force and efficiency characteristics of jellyfish-inspired flapping wings at ~103-104 Reynolds numbers during time-asymmetric flapping. It was indicated that the propulsion performance is optimized at a Reynolds number of 7000. Furthermore, reducing the time asymmetry coefficient and selecting an appropriate flapping frequency can enhance the coherence of large-scale vortices and delay the process of turbulence in the wake.
