Investigation of the controlled boundary layer concept on perforated walls was implemented in wind tunnel tests of well-known NACA 0012. Analysis of the obtained results allowed to check a number of fundamental conclusions on the possibility of wall interference reduction and to choose the optimal combinations of parameters characterizing these boundaries.
