A computational inverse procedure for transonic airfoils in which shapes are determined supporting prescribed pressure distributions, is presented. The method uses the small disturbance equation, and a consistent analysis-design differencing procedure at the airfoil surface. This avoids the intermediate analysis-design-analysis iterations. The effect of any openness at the trailing edge is taken into account by adding an effective source term into the far field. A systematic expansion procedure which models the far field for solid tunnel walls is presented along with some design results for the associated boundary conditions and those for a free field.(Buehn)
