Experimental studies of buffeting onset phenomenon physical picture on a model of a supercritical airfoil at transonic speeds are presented. Passive control method of this phenomenon based on application of the special jet vortex generators is given. It is shown that application of this method leads to delaying of the onset and decreasing of buffeting phenomenon, and at the result – to improve aerodynamic characteristics of airfoil.
