about the airfoil

Start - Trailing Edge


along top surface (Extrados)
towards Leading Edge





Leading Edge





along bottom surface (Intrados)
back towards Trailing



End - back to Trailing Edge




Coordinates

For top surface, Y is positive.
For bottom surface, Y is negative if it is under the reference line.
Between the x et y coordinates, the separator is at least one space

Attention :
- The first X must be 1.
- The last X must be 1.
