The turbulent transonic airflow over NASA SC(2)-0710 airfoil with a spoiler is studied numerically. Solutions of the Reynolds-averaged Navier-Stokes equations are obtained with a finite-volume solver. The solutions reveal a high sensitivity of flow pattern to values of the spoiler deflection angle, as well as to changes in the freestream Mach number Mбесконечность and angle of attack α. The existence of lift coefficient hysteresis in narrow bands of Mбесконечность and α is shown. Keywords: airfoil, transonic flow, shock waves, instability.
