Recent interest has sparked the revival of the airfoil plot program which has now been completely rewritten in a simplified version.

The airfoil plot program(AFP) will display an airfoil plot on the screen and also render the plot on a standard printer. In addition, a recent update will now allow the airfoil thickness to be changed and viewed and also allow the comparison of up to 5 different airfoils on the screen. Printer calibration is now automatic. The program should print on any A4 size printer, and possibly larger printers, although nothing larger than A4 has been tested.

Printed plots are generated to the chord size input at print time.

The current program will only accept coordinate files in the Selig/Soartech format, although most airfoils would seem to be already available in this format.

The latest install for afp can be found here.

A comprehensive library of airfoil coordinates is avalable in the Selig/Soartech format. Please copy and paste the following link into your browser address line in order to download the complete library in a zip file:
