Abstract

The paper focuses on airfoils with spoilers and high lift devices.  The investigation was carried out using experimental and numerical methods.  Results of two methods of visualization (Particle Image Velocimetry, Smoke wire) for three types of airfoils (two with different spoilers and one with a split flap) were extended by pressure distribution measurement for one airfoil.  The measurements were taken in open and closed circuit wind tunnels.  Pressure distribution, velocity profile and images of flow in the airfoil vicinity were evaluated from numerical computations.  The obtained data was prepared for mutual comparison and results were discussed.
