摘要：

The results of an experimental study of the perturbation development created by pulsed glow discharge on the swept wing surface with periodic distributed roughness along the leading edge at Mach 2 are presented. The influence of periodic roughness on the model surface on the excitation and development of wide-spectrum disturbances in the process of laminar-turbulent transition is determined. It was found that the mean flow modulation in the boundary layer of a swept wing with a sweep angle of 40 degrees leads to a strengthening of the oblique breakdown mechanism.
