It would be better that I've said "by avoiding partially turbulent airflux"
That still implies laminar flow, which isn't happening.
Reducing feather mass? Reducing feather total area?
No. Controlling the resistance to torsional deflection.
Not to the best of my knowledge. However, with the exception of mass
effects (and at very high lift coefficients), the wings would operate much
the same even if the individual feathers were shaped like planks,
With no effect on airflux?
