Abstract
A segment of the upper surface of a laminar airfoil model is submitted to forced vibrations at controlled frequency by means of piezo-electr ic actuators. The experiment carried out in a wind tunnel demonstrated an appreciable diminution of the profile drag for some ranges of the angle of attack and Reynolds number.
