Fig. 6. The rate of change of vertical force coefficient (Cv)
with angle of incidence (
'),
dCv/d
' for `early' and `steady' conditions
from
'=-20 to +20° for model hawkmoth wings with a range of
aspect ratios (AR). Bars show 95 % confidence intervals
(N=10). Differences both between high and low aspect ratios for
either condition and between `early' and `steady' conditions for each aspect
ratio are significant (P<0.01). The slopes of the regressions of
dCv/d
' against AR for `early' and
`steady' conditions are not significantly different and average 0.130.
