Abstract
The results of experimental studies of the physical pattern of the appearance of the buffet phenomenon at transonic speeds for a model supercritical profile are presented. A passive way of controlling this phenomenon is proposed that is connected with the organization of special jet vortex generators. It is experimentally found that the proposed approach leads to a delay in the appearance and weakening of the transonic buffet and, as a result, to an improvement in the aerodynamic characteristics of the profile.
