Title: Modified laminar NACA airfoils
Post by: 33Vortex on May 17, 2010, 07:19:48 PM

Do anyone happen to have airfoil data in the form of excel spreadsheets for the NACA modified 6-digit series? Specifically the 63A012 through 65A012.

It would save me tons of painstaking work of manually entering data. (http://hem.bredband.net/turnik/icons/icon_urrk.gif)

Thanks.

I assume you have a copy of Theory of Wing Sections by Abbot and Von Doenhoff?  It has all of the basic thickness forms and mean lines.  If you set them up on an excel spreadsheet, they don't take too much time.  Another resource might be the UIUC airfoil database. It doesn't have them all, but it has a few...

Hmm, no I do not have that book you mentioned. Maybe I should, thanks!

I'm using MultiSurface Aerodynamics and it does not allow me to export airfoil data in any format I can use in SolidWorks.  :frown:

What you can do is to draw the airfoil in a CAD program (I use SolidEdge 2D) and then import it into Solidworks.  I don't know of a way to make the task less labor intensive, but I draw mine out manually like this.  However, there are ways to manipulate airfoil data via text files, if you can copy and paste it that way.

Yeah, that is what I'm doing. 182 points of 7 decimal accuracy per airfoil.  :rolleyes:

Takes a while, and is very tedious work. I'll just continue the way I'm doing it now, making curves through xyz based on manually transferred spreadsheet data.

I still would strongly recommend a copy of that book.  $20 from Amazon I think.

Already ordered it thx. :)

Great book, it presents the history and math behind the NACA airfoils very well. I have all the data needed for these airfoils within this book. Thanks for the tip!

 :salute

Stoney: Did you ever look at SW macros for importing text into objects?

I haven't yet.  My F1 project got stalled, so I haven't taken it further.  I had planned on having SW so I could model everything.  I do know there is a way to do it, but I never did the research since I didn't have the software.  I did do some plots using Solid Edge 2D CAD, but that's as far as I got.

Right. I started working on LISP routines to do something similar and then started on another project (that pays money).
