A study has been made of the possibility of controlling 
the aerodynamic characteristics of airfoils with the use of local 
pulse-periodic energy supply to the flow near the contour of the airfoil 
in transonic modes of flight. The influence of energy supply of different 
intensity to the supersonic region on the structure of the flow and 
the wave resistance of the airfoil has been studied based on mathematical 
modeling. The flow is modeled based on the two-dimensional unsteady 
equations of gas dynamics.
