SUMMARY

The NACA 64A416/4416 mod airfoil data is not readily available due to its specific designation and limited documentation. Users can generate the coordinates using online tools such as the NACA airfoil generator found at Aeromech. For practical applications, particularly in modeling for the DeHavilland DHC-2 Beaver, users can find alternative airfoils with available data. Additionally, methods for coding the generated data into AutoCAD and Rhino are accessible through online resources.

PREREQUISITES
  • Understanding of NACA airfoil designations and their significance
  • Familiarity with airfoil coordinate generation tools
  • Basic knowledge of CAD software, specifically AutoCAD and Rhino
  • Experience with online data retrieval and image generation
NEXT STEPS
  • Research "NACA airfoil generation algorithms" for coding solutions
  • Explore "AutoCAD NACA profiles" for specific drawing techniques
  • Investigate alternative airfoils suitable for large-scale models
  • Learn about "airfoil data representation" for better modeling accuracy
USEFUL FOR

Aerospace engineers, model aircraft designers, and hobbyists working on large-scale models of aircraft, particularly those interested in NACA airfoil specifications and CAD applications.

Hello,

I am looking for coordinates data for the airfoil NACA 64A416/4416 mod. This airfoil was used on the DeHavilland DHC-2 Beaver. While the airfoil is listed on various manufactures lists no data, or image, of the airfoil is available. Can you tell me whether there is a reason this data is not given, or am I misunderstanding something. And, is there an alternative airfoil which can be used and where the data and an image is available. The information is required for a large scale model of the DHC_2 Beaver up to 140 inch wing span.

Regards,
Spud

Hi Baluncore,

I visited aeromech and found that by entering either 4416 (4 Series) or 64a416 (6 series) I finally get an image representation of an airfoil, plus its data. The other databases on the web don't produce either for the designations above. I don't know why but its a pity that they dont. All I need now is a method of coding the data for AutoCAD and Rhino so that the airfoil is automatically drawn. Many thanks for your help, it is very much appreciated.

Regards,
Spud
 
Google; 'autocad naca profiles'
There appear to be several available.
