Institution National Research Council Canada, National Aeronautical Establishment, High Speed Aerodynamics Laboratory Date 1979-04-30 Abstract The wind tunnel wall interference in transonic speed is formulated as a perturbation to the basic flow around the airfoil in free air. The perturbation equation is derived from the transonic small disturbance equation and is linear but with variabie coefficients containing the non-linear solution of the basic flow. The equation is solved numerically by a direct matrix method using the classic al boundary condition for aporous wall. The solution in terms of lift versus angle of attack agrees well with that calculated directly from the small disturbance equation.
