Aeroelastic tailoring is defined as "the embodiment of directional stiffness into an aircraft structural design to control aeroelastic deformation, static or dynamic, in such a fashion as to affect the aerodynamic and structural performance of that aircraft in a beneficial way",[1] or "passive aeroelastic control".[2] Objectives associated with aeroelastic tailoring include weight minimization, flutter, divergence, stress, roll reversal, control effectiveness, lift, drag, skin buckling, and fatigue.[3]
