] Aerodynamic washout
Generally speaking any type of washout is not the ideal approach.
Washout is used to compensate for bad planform design.
I have to disagree here. For a given tip stall margin,
a slight amount of washout (1 degree or so) allows using
a stronger taper. More taper has all
If you're designing a wing with a flat-bottomed airfoil, it's
convenient to create the effect of washout by thinning the airfoil
as you go out from the root; this reduces camber and lowers the angle
of attack at which CL = 0. So for example Mark Drela's Allegro 2M
uses an 8.7% AG35 at the root,
I think we are agreeing on the aerodynamics, but disagreeing on the
applications.

Hi Oleg, this may seem unusual to you. I suggest you fly one of my planes and then you drop me a line. Or betterr yet make a wing as I do. Talking too much about theory will make you falling off a thermal. Mike
