elastic axis

A spanwise line along the cantilever wing. Along this line, a load will produce bending but not torsion. The illustration shows an example of an elastic axis of a wing when it encounters gust. See also aileron reversal.
If an up-gust strikes the wing an increase on angle of attack results. Increased lift acts through the aerodynamic center. The wing twists nose upward about its elastic axis located some distance behind the aerodynamic center. This increases the angle of attack and lift even more and the self-perpetuation continues.
