CONTROL OF TRANSONIC FLOW ABOUT AIRFOILS BY MEANS OF PERIODIC PULSE LOCAL ENERGY SUPPLYS. M. Aul'chenko, V. P. Zamuraev, and A. P. Kalinina UDC 533.6.011 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.
