For the grant of the Grant Agency of the Czech Republic „Subsonic flutter analysis of elastically supported airfoils using interferometry and CFD“ new airfoil model NACA0015 was constructed and manufactured. Profile is divided in five parts and inside is the replaceable elastic element, which enable the pitch angle changes. Inside the body there is also pitch angle sensor and four semiconductor pressure sensors. The second degree of freedom is allowed by the plunge of the structure with the airfoil and centered its position by two feathers with position detected with the magnetic sensor. The whole arrangement of the experiment was described with all details in [2].
