Abstract

The evolution of the artificial wave packet in the inhomogeneous supersonic boundary layer of swept wing was experimentally studied for the first time by hot-wire measurements. To create an inhomogeneous flow in the boundary layer of the swept wing, periodic stickers of various shapes were used. The localized disturbances were generated by pulse glow discharge. Analysis of the mean flow, integral dependences and the averaged waveforms of wave packet in supersonic boundary layer of swept wing has been executed. The stickers used in the experiments produced modulations of the swept wing boundary layer with amplitude equal about 30% from the incoming flow. Inhomogeneity of the mean flow transforms the wave packet, its development slows down somewhat.
