Discussion Overview

The discussion revolves around the availability of coordinate data for the NACA 64A416/4416 mod airfoil, specifically in the context of its application in modeling the DeHavilland DHC-2 Beaver. Participants explore the reasons for the lack of data and potential alternatives for obtaining or generating the required airfoil information.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • Spud inquires about the absence of coordinate data for the NACA 64A416/4416 mod airfoil and seeks clarification on whether this is due to a misunderstanding or a specific reason.
  • Some participants suggest generating the airfoil coordinates using online tools and algorithms, referencing resources such as Wikipedia and specific aerodynamics websites.
  • Spud reports success in obtaining an image representation and data for the airfoil using the aeromech website but expresses frustration over other databases not providing the same information.
  • There is a request for assistance in coding the airfoil data for use in AutoCAD and Rhino software.
  • Another participant suggests searching for existing resources related to AutoCAD NACA profiles, indicating that there may be multiple options available.

Areas of Agreement / Disagreement

Participants generally agree that the airfoil data can be generated using available online tools, but there is no consensus on why the data is not readily available in other databases. The discussion remains unresolved regarding the specific reasons for the lack of data in certain contexts.

Contextual Notes

Limitations include the potential variability in the accuracy of generated airfoil data and the dependence on the specific algorithms used. The discussion does not address the completeness or reliability of the alternative resources mentioned.

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.
