N2 - An experimental study of effect a pair of weak shock waves on the supersonic boundary layer of a flat plate with a blunt leading edge with Mach number M = 2.5 and zero angle of attack was performed. The radius of bluntness of the leading edge was r = 2.5 mm. The measurements were carried out using a hot wire anemometer. The paper presents a complex flow structure on the surface of the model with a blunt leading edge. It is found that the supersonic boundary layer on a flat plate with a blunt leading edge is very sensitive and susceptible to the effect of a pair of weak shock waves. High-intensity peaks were found in the regions of the disturbed flow. It is specially noted that the largest level of mass flow pulsations in the boundary layer occurred under the effect of a trailing edge of a weak shock "N-wave".
