Description	The contribution presents results of optical measurements of flow field around a self-oscillating double circle (DC)18% profile elastically supported in a measurement section of a wind tunnel. In a lower frequency range, the profile can vibrate like a dynamic system with two degrees of freedom with translation and rotation. The schlieren and interferometry methods were used for visualization of a two-dimensional flow in different phases of the profile motion. The total aerodynamic force, pressure and flow velocity on the profile surface were evaluated in given time instants.

(en) Článek prezentuje výsledky optických měření proudového pole kolem samobuzeně kmitajícího dvoukruhového DC 18% profilu pružně uloženého v měřícím prostoru aerodynamického tunelu. V nižším frekvenčním pásmu profil může kmitat jako dynamický systém se dvěma stupni volnosti pro translaci a rotaci. Pro vizualizaci 2D proudění v různých fázích pohybu profilu byly použity metody šlírová a metoda interferometrická. Na povrchu profilu byly v předem daných časových okamžicích vyhodnoceny celkové aerodynamické síly, tlak a rychlost proudění (cs)
