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.

WebJan 1, 2009 · Initially the micromechanical flying insect (MFI) project aimed for independent control of wing flapping and rotation using two actuators per wing. At resonance of 270 … WebCareful attention to mechanical design of the thorax and wing structures, using ultra-high-modulus carbon fiber components, has resulted in high-lift thorax structures with wing drive frequencies at 110 and 270 Hz and adequate power delivery at high wingbeat frequencies is estimated.
