Development of the Junkers-diesel Aircraft Engine
A 1930 technical report on the Junkers diesel aircraft engine, issued through the NASA Technical Reports Server with a record that gives no further detail on its makers or readership. The pictures are line-drawn engineering plates: cylinder and piston cross-sections, a multi-cylinder engine elevation, a valve or governor detail, and a performance graph of pressure against r.p.m. A designer could take the clean, labelled diagram style and the sectional drawings as a model for technical illustration.
