How is washout built into a fibreglass foam core wing of a GA Airplane with 40% span flaps, 40% span ailerons.
Does the angle of incidence change gradually over the span of the wing, or is the airfoil rotated downwards to reduce the angle of incidence eg. at the wing airfoil joints and then just flared, eg. over the span of a 1m to a matching trailing edge?
Eg 20% span root wing aifoil incidence no flap, 5deg; 40% span mid wing airfoil incidence with flap, 4 deg; 40% span wing tip airfoil incidence with aileron, 3 deg
