The experimental investigations results of the flow over a straight wing model, placed at the subsonic wind tunnel are presented. The model was installed at high angle of attack so that the flow separation have place near the leading edge. An influence of external disturbances on such flow is studied. Free stream disturbances were generated by thin wire stretched in front of wing model. It is found that the separation can be completely removed when the wire wake achieve a wing upper surface.
