Are you sure it's Nasa and not Naca?

Hi,

You can get some excel files from this discussion forum. Someone made both 4 and 5 digit NACA excel files to get coordinates.

Hope that helps, took me a while to find these and I am very pleased with them.

Have you also checked Profili? My copy is on my other computer so can't look for you, but if you don't have it its free for the basic version and you can get the airfoils at the very least. Paid version is very cheap for what you get

It's definetly "NACA" and not "NASA" but that's a minor detail.

0030 is 30% thick. I can't think of anything on a Yak 50 that is 1/3 as thick as it is wide. Even the rather thick tail surfaces are only MAYBE 20% thick. You might want to confirm your information source with another one or two options.

The thick airfoils are often used for wheel pants and such. They're perfectly valid.

They are Andy. But there's no wheel pants on a Yak 54.

Glueit, I found a coordinates generator at;
http://www.ppart.de/aerodynamics/profiles/NACA4.html

There also used to be some freeware easy to use 4 digit airfoil plotting programs. There's still a few out there but they are so old that my Windows 7 system won't let me install them. And I'm not ready to figure out how to install and run them in a back dated mode or if it'll let me.

But I've found that the best way is to download and install Profili2. The freebie version allows you to generate coordinate files for new 4, 5 and 6 digit NACA airfoils and then print them or export DXF files of the plot into a CAD program. If you want more than that it's quite inexpensive to pay for unlocking the more advanced features.
