Compressible flow about symmetrical Joukowski profiles
This is a 1938 NASA technical report on compressible flow about symmetrical Joukowski airfoil profiles, produced for aeronautical engineers and researchers. The three pictures are mathematical diagrams: a circle with offset centres and their mapping, a Joukowski profile drawn in a complex plane, and a simple source image about a circle, all in thin black line on white with labelled axes and points.
