Flow past the airfoil of a civil aircraft wing is numerically modeled in the transonic buffeting regimes. The characteristics of unsteady self-oscillations of the shock on the upper surface of the airfoil are studied. To suppress them a technique of controlling the flow is proposed. It consists in blowing a jet tangent to the upper surface of the airfoil from a small-size slot nozzle. The calculations are carried out within the framework of the unsteady Reynolds equations.
