Description	The contribution presents the designed aeroelastic model, experimental set-up and preliminary tests of optical measurements of flow field around a vibrating NACA 0017 profile elastically supported in the measurement section of the wind tunnel. The profile can vibrate with two degrees of freedom for translation and rotation. The interferometry method combined with the high speed filming was used for flow visualization of in different phases of the profile motion. The measurements were performed in a subsonic wind tunnel above the airflow velocity for loss of the system stability by flutter, thus the vibration amplitudes were relatively large up to about 7 mm for vertical translation and 16.5 degrees for angle of rotation around the elastic axis. The 52 images of the flow field were recorded during one oscillation period of the profile from which the pressure and velocity can be evaluated in the given time instants.
