"The documents were so old, however, that they were not listed in the modern computerized library search systems, and some of these documents were out of print." ¹

NACA Cleveland library, circa 1945.

Summary

I can usually get even rare and obscure publications through inter-library loan from my public library, but these were reported as having no loanable copies available.

Discussion

I have tried the many excellent search tips at Gwern's Internet Search Tips, and now I am at the "request help" stage.

I would appreciate any help anyone can offer finding them as loanable print copies or digitally.

Recently made available

• Heat Transfer Calculation for Aerofoils RAE Rep. No. Aero. 1783, Nov. 1942. Reprinted as NACA MRR No. 3E29, May 1943.
  I requested it through airsciences.org.uk and they sent me a scanned pdf copy (not sharable, so you will have to request your own copy).

Could only find at google books

• NACA conference on some problems of aircraft operation [at] Lewis Flight Propulsion Laboratory, Cleveland, Ohio, November 17, 18 1954 books.google.com

Might be available online soon

Could not find except by reference

I have found one-line references to these, but no on-line sources (ntrs.nasa.gov, google, worldcat, dtic, semanticscholar, archive.org, etc.), nor loanable library copies.

On a list of restricted/classified NASA reports

We may never get to see these, unless one has a security clearance and a "need to know". (Must be some really good info to still be restricted 80+ years later.)

However, I have seen copies of some other publications that are on this list, so things may have changed, and they might someday be available.
