This paper describes designs of the gust load alleviation (GLA) system and its wind-tunnel tests. The objective is to verify the effectiveness of control system syntheses which we have examined theoretically in the active flutter suppression (AFS). Applying the syntheses to the GLA system of a cantilevered elastic rectangular wing, the 1st or the 2nd order controllers can be constructed. It is shown in the wind-tunnel tests that the bending moment at the wing root is reduced to 66.2% of the control-off value as the best by using a designed reduced-order controller. Furthermore, the robustness for the parameter perturbation of the plant is verified in the tests where the wind velocity is 50% higher than the designed wind velocity.
