Keywords: flapping wing, insect, wing twist, low-reynolds-number
The effect of spanwise twist on the performance of a flapping wing is studied using three-dimensional computational methods. Sinusoidal flapping and feathering motions are imposed, with the feathering angle varying linearly along the span to create twist. The lift, power and efficiency are computed and related to the flow structures.
