Development of the rules governing the strength of airplanes. Part III : loading conditions in France, Italy, Holland, and Russia - aims at standardization
A 1933 NASA technical report comparing airplane strength loading rules across France, Italy, Holland and Russia, aimed at standardizing aircraft design requirements for engineers. The single picture is a technical chart plotting load factor against gross weight in tonnes, with numbered curves tracing each country's rule, useful to a designer only as a plain engineering graph of falling curves on a gridded field.
