“…These airfoils were designed using the BGK full-potential code with a coupled boundary-layer method, (Bauer et al, 1977), combined with wave-analysis diagrams. The diagrams supplied the designer with a graphical picture of the effect of surface slope modifications and aided in the iterative development of an airfoil shape (Eggleston, 1977). The resulting family of airfoils is shown in Figure 3.…”
