Wing load alleviation is a crucial aspect in aircraft design for improved structural efficiency. Typically, movable surfaces are employed to lessen aerodynamic stresses during maneuvers, thereby reducing structural weight. This study evaluates aileron- and winglet-based strategies on a civil transportation aircraft, focusing on allowable reductions in wing bending moment/shear while adhering to structural stiffness constraints to prevent aeroelastic instability within the certification flight envelope. Analyzing different geometrical settings for the involved alleviators, trends in elastic aircraft behavior have been identified, offering insights into the benefits and drawbacks of each investigated alleviation strategy.
