As Boeing’s 787 illustrates, airliner wings are more slender than they used to be. But as wings get slimmer in pursuit of lower drag and lighter weight, flutter becomes a greater concern.  Flutter is the potentially destructive coupling between aerodynamics and structural dynamics. It is normally avoided by making the wing stiff enough so that speeds at which gusts or control inputs excite its bending and twisting modes are outside the aircraft’s flight envelope.  But ...
