Talk:Theodore Theodorsen

Expanding on Significant Themes
The theory of arbitrary airfoils Reference Material is located : http://ntrs.nasa.gov/search.jsp?R=528247&id=1&qs=Ns%3DPublicationYear%257C0%26N%3D4294755735 Abstract:This report gives the exact treatment of the problem of determining the 2-dimensional potential flow around wing sections of any type. The treatment is based directly on the solution of this problem as advanced by Theodorsen in NACA-TR-411. The problem condenses into the compact form of an integral equation capable of yielding numerical solutions by a direct process. —Preceding unsigned comment added by Gaccolla (talk • contribs) 22:32, 10 December 2007 (UTC)

National Advisory Committee for Aeronautics Section
Because of my lack of writing ability in this fourm I would Like someone to add this reference. Again I am more a computer person than a writer. I found this section that Backs up his work at the NACA and even may shed more light on his mathmatical ability. the Link is: http://history.nasa.gov/SP-4305/ch4.htm (section 107)

"Relativity" section
I've deleted this section because it seems to be an attempt to re-create the essential elements of an article about Theodorsen's views on relativity that was deleted after an afd debate - see here.

The admin comment on deletion was that a small referenced comment could be added to the Theodore Theodorsen article. That's small and referenced and comment. Not a short polemical article embedded within the main article.

Then reduce it to what you consider the appropriate size, not delete it. DGG (talk) 00:18, 26 November 2007 (UTC)

I would have done if I had any accurate information - please read the recent afd on this subject. All we know is that Theodorsen wrote an article that nobody took any notice of. It's not even clear where it was first published. One editor is currently trying to track it down. andy (talk) 07:42, 26 November 2007 (UTC)

As discussed in the AfD debate referred to above, I have now added a short paragraph on the relativity paper, with references. JohnCD (talk) 23:04, 9 December 2007 (UTC)

Proposed "Patents" section
Since Andy has taken a great interest in editing everything in this article I will now post information to the discussion page for anyone to post in the article. I would like to include reference to his many Patents by number. This would include numbers; 2270912, 1981007, 2951662, 3032976, 2081963, 2172333, 2172334, and 2330803. —Preceding unsigned comment added by Gaccolla (talk • contribs) 14:35, 27 November 2007 (UTC)


 * Gaccolla, you really need to read up on the rules for WP articles because you seem unsure about what's "allowed" to be included. If you are sure that a section outlining key patents and giving useful references enhances the article then why not include it? You don't need anyone's permission. If other editors disagree they'll alter the section or even delete it, but that's how WP works. Please read WP:POLICY and some of the key policies and guidelines, particularly WP:NOT, WP:VERIFY and WP:NPOV. andy (talk) 15:43, 27 November 2007 (UTC)

Verifiability
The only adequately referenced biographical material that I can find is the following:

Theodore Theodorsen (1897-1978) earned an engineering degree from the Norwegian Institute of Technology at Trondheim, Norway in 1922 and later earned a doctorate in physics from John Hopkins University.

He joined NACA in 1929 and was appointed the head of the Physical Research Division at Langley Aeronautical Lab.

He worked on airfoil theory, fire prevention in aircraft, theories of wind tunnel design, and engine cowling improvements.

He left NACA after World War II. ("Theodore Theodorsen," biographical file, Lek 8/3/2 #002289, NASA Historical Reference Collection, NASA History Division, NASA Headquarters, Washington, DC.)



Dr. Theodore Theodorsen, Ph.D., Physics, Johns Hopkins U; formerly consultant Air Research, U.S. Research and Development Command; Vice President and Dean of Engineering, Tech. Inst. of Aeronautics, Rio de Janeiro; Consultant, Sikorsky Div. of United Aircraft; Chief of Physical Research of NACA at Langley Field 1929-1946; originator of exact theory of pressure distribution on airplane wings; theory of wing-flutter; theory of dual propellers; structure of turbulence; author of numerous technical papers; Fellow and founding member, IAS.



I propose to remove all unreferenced material from the article and re-build it based on the above.

Source material
I am starting to wonder if much of this article was cut and paste from somewhere else. See, for example, "The ensuing years were highly productive ones for Theodorsen in a great variety of experimental and theoretical areas as the list of publications arranged chronologically and appended herein discloses" and "who became one of father's lifelong friends."

Also, we need a lot more source citations. I found one, there must be others. Rees11 (talk) 21:38, 30 October 2009 (UTC)
