A Navier-Stokes computation method has been extended to consider turbulent transonic flow about lifting airfoils in free air. A brief description of the computational methods is given and results are compared with experimental data. The most striking feature of the calculations was that, in some cases, unsteady periodic motion was obtained along the aft portion of the airfoil and in its wake, even though the airfoil and boundary conditions were stationary. Recent experimental results for the same airfoil indicated oscillations downstream of the shock at a frequency near that which was calculated, but with a significantly small amplitude.
