DESIGN OPTIMIZATION OF TRANSONIC AIRFOILS [PDF]
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.
