MBDR is a field that has been extensively studied in Developers turned to Full Potential codes, as panel methods could not calculate the non-linear flow present at transonic speeds.The first description of a means of using the Full Potential equations was published by Earll Murman and Julian Cole of Boeing in 1970.Frances Bauer, Paul Garabedian and David Korn of the Courant Institute at New York University (NYU) wrote a series of two-dimensional Full Potential airfoil codes that were widely used, the most important being named Program H. The next step was the Euler equations, which promised to provide more accurate solutions of transonic flows.
