Effect of Wing Membrane Material on the Aerodynamic Performance of Flexible Flapping Wing

Flexible deformation of the insect wing has been proven to be beneficial lift generation and power consumption. There is great potential for shared research between natural insects bio-inspired Flapping Micro Aerial Vehicles (FWMAVs) performance enhancement. However, aerodynamic characteristics process flexible flapping wing, especially influenced by membrane material, are still lacking in-depth understanding. In this study, wings with different materials have experimentally investigated. Power input force were measured evaluate influence material. The rotation angles at sections extracted analyze process. It was found that higher elastic modulus could generate more but cost power. A lower means shows an advantage in loading. Twisting obvious flexibility. Additionally, flexibility also attenuate angle fluctuation, which turn enhances efficiency. paper helpful further understand design FWMAVs performance.
