Abstract
The paper discusses experimental results on the wave train development in a longitudinal trace in the flat plate boundary layer at Mach 2.5. An analysis of the spatiotemporal distributions and frequency-wave spectra of pulsations, as well as their wave characteristics in the linear and weakly nonlinear phase of the wave train development in a homogeneous and inhomogeneous boundary layer at a fixed power of the controlled disturbances source has been carried out. During the analysis of the results, no subharmonic resonance was observed. Expansion into the wave spectrum of a stationary inhomogeneity and experimental data on wave characteristics and disturbance spectra made it possible to propose options for wave interaction for oblique breakdown.
