An oscillating trailing-edge flap of a rigid aerofoil is investigated, to gain a better understanding of the unsteady aerodynamic phenomena of lift increase due to trailing-edge flap oscillations. Therefore, the contribution of lift due to circulation and "added mass" effects are studied in an experimental approach. The unsteady aerodynamic forces and the unsteady flow fields are measured.
