The *.README file explains the simple-sweep transformations and corresponding 2D flow conditions that apply.
The *.fit.p3d files contain the set of discrete points in Plot3D format. Both the Sharp and the Blunt TE airfoils are included in this file.
The *te.txt files contain the set of discrete points in text format.
The *.igs file is an IGES file which contains the two airfoil sections. The *.p3d and *.te.txt points reside on the IGES analytic shape.
The *.pdf file provides some airfoil geometric characteristics and compares the two sections.
