High lift force with 275 hz wing beat in mfi

WebDec 21, 2024 · Furthermore, the bionic design of wings the prototype was carried out, therefore the wings can generate a high lift force in the flapping process. The experiment demonstrated that the aircraft can achieve a flapping angle of 160 degrees and 30 Hz flapping frequency. WebA key challenge is generating appropriate wing trajectories. Previous work [1] showed a lift of 506 µN at 160 Hz using feedforward control. In this paper, refinements to the MFI design including those in [2] increased wing beat frequency to 275 Hz and lift to 1400 µN using pure sinusoidal drive for a fixed benchtop experiment.
