Kabát Engineering s.r.o.



NACA Airfoil Generator is an addin for Autodesk® Inventor® which allows the user to generate Airfoil directly to the 2D Sketch.

This addin saves tons of time in:

  • generating wings, ailerons
  • modeling aircraft propellers and wind turbines
  • optimizing water pump, fans and turbines blades
  • reducing the pressure drop
  • eliminating Karman vortex street in objects in tubes and pipes
