Description:

Tk interface to the airfoilGen script

This script provides a way to generate NACA 4-Series airfoil geometries within Pointwise without relying on external coordinate files. Simply input the 4 digits defining a NACA 4-Series airfoil and click CREATE.

For those unfamiliar with the NACA 4-Series geometry:

  1. The 1st digit is the maximum camber
  2. The 2nd digit is the maximum camber location
  3. The 3rd and 4th digits represent the maximum thickness

Note:

  • All digits are a percentage of the chord length
  • Maximum thickness occurs at 30% of the chord
  • Chord length fixed to a unit length
  • All airfoils have a flat trailing edge

Example, NACA 2412:

  • Maximum camber is 2% of the chord
  • Maximum camber located at 40% of the chord
  • Maximum thickness is 12% of the chord (located at 30% of the chord)
