Fig. 6. (AC) Temporal distribution of vertical force augmentation for three
kinematic patterns and (D) mean vertical force augmentation during
clap-and-fling wing beat. Data are plotted as the difference (21)
between the performance of one (1) and two (2) flapping wings. (AC)
Kinematic patterns (pictograms) produced the same mean vertical force
coefficient during wing motion (
1.51). (D) Mean values (red) ±
s.d. (grey) of all 17 kinematic patterns. Force peaks are labelled according
to Lehmann et al. (Lehmann et al.,
2005).
