I've noticed some papers of potential interest have been recently added to the NASA web site at http://ntrs.nasa.gov/search.jsp . Many of these are translations of German or other European reports.

Some examples are listed below.

Only looked at a few so far, but they're well translated!

Further to Bob's listings above, another of these reports which might be of interest is an account by a German author on some of the technical aspects of the Schneider Trophy races (1913 - 1931). It has been translated into English.

If you go to the Home Page of the website http://ntrs.nasa.gov and type "NACA-TM-712" into the search box, the report should download as a 47 page doco PDF. It is quite well illustrated with photos (not too clear) and charts etc.

Another interesting report is available at:

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19930094473_1993094473.pdf

This is a translation of an Italian paper on their engines developed for Schneider Trophy racing planes. The AS6 was a rather ingenious design, achieving high power with minimal frontal area and probably representing the first successful application of the contra-rotating propeller concept.
