摘要
The paper is devoted to an experimental study of laminar-turbulent transition and instability disturbances evolution in a three-dimensional supersonic boundary layer on swept wing with sharp leading edge. The detailed data of natural disturbances development are obtained for the first time Characteristic zones of disturbances evolution are determined. A position of instability region of secondary flow is experimentally defined Some features of disturbances evolution, characteristic only for a supersonic boundary layer are revealed It was shown experimentally that secondary cross-flow instability plays the main role in laminar-turbulent transition in 3-D supersonic boundary layers.
