Abstract
Abstract
The paper is devoted to the investigation of the flow and effects taken place when three-dimensional roughness element is placed on the leading edge of the trapezoidal flying wing. The experimental study was carried out in the working park of the subsonic wind tunnel. Low Reynolds numbers allowed running experiments at in-flight-like conditions. Pictures of the flow structure were obtained by liquid crystal thermography. It was found that longitudinal disturbances on the leading edge and behind three-dimensional roughness element form differently. Inner configuration of the longitudinal structure was shown by hot-wire measurements.
