Hi,

I have the following information about an airfoil shape:

NACA 66 camber height/chord length=0.2 thickness/chord=0.09

Is this a complete definition of a certain airfoil ? Has this airfoil a certain number in the NACA numbering system ?

Does someone know a place where to get the coordinates of that airfoil ?

Thanks in advance,

Mark

Hi,

I forgot an additional information about that airfoil shape:

NACA mean line a=0.8

Regards,

Mark

Hi Mark,

Try this book "Theory of wing sections" by Abbott and Von Doenhoff, I think the ISBN is 0486605868. This book has a complete list of coordinates for lots of NACA aerofoils and alot of experimental wind tunnel results. Hope this is of use to you,

Mark.

I have that book, but I can not identify the profil number out my given geometric values. There is a NACA 6-series, but the numbers contain also information about the lift coefficient, but I have only geometric parameters.

Thanks,

Mark

Hi Mark,

Have a look at the original NACA-report Nr. 824. You can it download from

http://naca.larc.nasa.gov/reports/1945/naca-report-824/

There you should find all the necessary information.

Best regards

Markus
