Free plans? Open source plans?

I don't think you know what open source means.

Most aviation advances have been held strictly secret, either by
companies or by governments. Nobody advertises their advances to their
potential adversaries.

The Wright brothers took to the air on wings that had an airfoil that
had evolved from the experiments of Otto Lilienthal, which they read
about from Lilienthal's own writings. *Their wire and strut braced wing
evolved from early experiments and designs of Octave Chanute, who not
only freely shared his discoveries with the Wrights, he visited them at
least once. *In fact, Chanute organized an international conference to
share information on aeronautics. *The Wright brothers were keen to
patent their advancements, not keep them secret. *It is pretty hard to
keep something secret when it is in plain sight for all to see, like for
example Bleriot's modern tractor design which quickly eclipsed flying
bedsteads like the Curtiss and the Wright flyer. *After World War one,
when the US realized any lead they had in aviation was not only history
but they were now way outclassed, people like Gugenheim and the US
government (through NACA), went out of their way to foster open sharing
of information. *Guggenheim did it by bringing top flight theorists to
the US (students of Rankine, Prandtl and Froude) to teach and NACA did
it by systematic experimentation and dissemination of the results. *This
pretty much continued up until WWII. * * *In fact, I have papers and
books from US efforts during WWII that not only reference the pre war
work of Japanese researchers, but laud them.

Was NACA and Guggenheim paying these people to collaborate?

If so, how is that open source like the open source software movement?
No one is getting paid to share their knowledge in open source. You
have to share your knowledge without compensation -- that's how it
works. You don't sell your hard won knowledge. You give it away so
others can benefit from it.

What about WWII and after? Sharing open source super sonic secrets?

Anyway that's a lot of ******** and besides the point.

Open source software projects are often poorly tested pieces of half
working junk written ad hoc and often by very immature, inexperience
developers. The Linux kernel is an exception. Apache is an exception.
For each of these there are 10 thousand pieces of crap.

You're free to share and collaborate all you want. Go for it.
