Airfoils of three Czech-designed sailplanes and their wing-fuselage interaction were subject to study. The combination of experimental results with those of numerical modeling greatly facilitated the understanding of the various phenomena. The effects of several passive flow control devices, vortex generators, counter-rotating vortex generators, and zig-zag type turbulators were considered. Separation suppression was reached and consequent drag coefficient reduction of test aircrafts measured in flight. Investigation was further extended by PIV Time-Resolved technique.
