1. In 1970, Magnus and Yoshihara published a transonic solution for a practical lifting airfoil with embedded shock. See R. Magnus and H. Yoshihara, "Inviscid Transonic Flows Over Airfoils," AIAA J. Dec. 1970, pp. 2157-2162. Murman and Cole's relaxation algorithm, which calculated solutions to the transonic small-disturbance potential equation for supercritical flows about 2D airfoils, soon followed. See E.M. Murman and J.D. Cole, "Calculation of Plane Steady Transonic Flows," AIAA J., Jan. 1971, pp. 114-121.
