An oscillating rig consisting of 'two-dimensional' aerofoils enclosed between two vertical wind tunnel walls, is capable of generating upwash and/or streamwise sinusoidal gusts. This design has certain advantages over some previous unsteady flow wind tunnels. The upwash velocity predicted from potential flow for aerofoil pitching oscillations, is in reasonable agreement with that obtained from the experiment.
