Fig. 10. Lift coefficients are plotted as functions of time for a one-winged fling half-stroke. The letters i–vi along the x axis correspond to the times the streamlined plots labelled i–vi in Fig. 7B were drawn. The angle of attack during pure translation was set to 45°. The Reynolds number (Re) was varied by changing the translational velocity of the wing from 0.00375 to 0.06 m s^–1. The first peak in lift corresponds to the lift forces generated during wing rotation. The second peak corresponds to the lift forces generated during translational acceleration. For Re=64 and above, lift coefficients fall as the leading edge vortices separate from the wings.
