Airfoil design via cubic splines - Ferguson's curves revisited [PDF]
, 2007 Few aerospace design topics have had so many pages devoted to them as airfoil parameterization. Claims of novelty must therefore be made with caution in this area, so we declare our starting point simply as a fresh perspective on legacy techniques ...

DESIGN OPTIMIZATION OF TRANSONIC AIRFOILS [PDF]
Engineering Optimization, 1993 Numerical optimization procedures have been considered for the design of airfoils in transonic flow based on the transonic small-disturbance (TSD) and Euler equations. A sequential approximation optimization technique was implemented with an accurate approximation of the wave drag based on Nixon's coordinate straining approach.
