In this work the results of experimental research of air flow near to the blunted body are presented. Experiments are carried out for models of a blunted body with the forward blunted surface of three types: with a porous mesh material with continuous permeability; with a porous mesh material with an impenetrable insert along a critical line; from a sheet material with the tangential microchannels, made on technology of deforming cutting. For the given models by means of PIV the air flow characteristics are measured at variation speed of air flow, and blow intensity.
