Abstract: Results of an experimental study of density-wave characteristics in the shock layer are presented for the case of a hypersonic nitrogen flow around a model with a two-dimensional compression surface, which is an arc of a circle, and a sharp leading edge. Controlled periodic disturbances developed on the streaky structure are registered by the electron-beam fluorescence technique. The streaky structure of the type of two vortices rotating in the opposite directions is generated in the shock layer by an oblique gas-dynamic whistle.

Keywords: hypersonic flow, streaky structures, shock-layer stability.
