Barrio, J. Fernández (author), Mertens, C. (author), Ragni, D. (author), Sciacchitano, A. (author), van Oudheusden, B.W. (author)A proportionate controller is investigated experimentally for unsteady load alleviation purposes on a 2D wing model with a trailing-edge flap. The controller acts on the velocity of the flaps, and pressure sensors are used to detect the unsteady loads, which are generated by actuating the wing model in a sinusoidal motion. Two different...journal article 2020
