Fair enough, but the wing is behaving in exactly the same way.

The wings of fixed-wing aircraft behave the same way whether they are
gliders or powered.

Nope. The lift/drag vectors are different as the AOA
changes. The rest of Bernoulli/Newton still apply. For helicopter and
autogyro blades, the lift/drag vectors are similar except that in
autorotation there are propeller and autorotative regions of the
rotor.


OK, take your workd for it, but I thought Autogyros had pretty much
straight blades. Alpha is obviously going to be relative to distance to the
hub if the alpha is positive, but even so, you could look at it the same as
washout if I'm following you correctly.
