Effects of Chord Wise Flexibility of Flapping Wing on Aerodynamic Force Generation

Debopam Das


In this work, the effect of flexibility of the wing is duly observed and the significance of this parameter at different Reynolds number and frequency ranges are well notified. It is seen that the in all or most of the cases of force generations the butterfly shaped wing gives the most efficient results, followed by the consistency of the rectangular wing of AR=2. The most rigid and the most flexible wings sometimes switch their efficiencies from maximum to low depending upon the Reynolds number ranges or the frequency of operation. But for a wider range of advance ratio it is very evident that the increase in flexibility or decrease in AR helps in producing more lift and thrust forces.
