This paper summarizes the wind-tunnel experiments on the active control technology that have been conducted in the large low-speed wind tunnel of the National Aerospace Laboratory. The experiments include a gust load alleviation (GLA) and two active flutter suppression (AFS) tests. A wind-tunnel model of the cantilevered elastic wing is designed to simulate an energy efficient transport. The model has two control surfaces, which are individually driven by small electric torque motors. In the GLA tests using the Dryden-type random gust, 25% reduction of bending moment in rms values at the wing root was attained by a single surface control. In the second AFS test, flutter boundary was raised by 13% in speeds when two control surfaces were activated simultaneously. It was found that the leading-edge control surface was effective for the AFS.
