The development and evaluation are presented of a numerical solution to the transonic airfoil problem. The scope is restricted to symmetrical airfoils at zero incidence angle in an inviscid flow field. The small perturbation relationship and the irrotationality condition are selected for the set of governing equations and the set is reduced to a system of ordinary differential equations by the method of lines. Solutions to this system are compared to experimental data on subcritical, critical, and supercritical airfoils and against the exact solutions to the subsonic and supersonic infinite wavy wall.
