Light aeroplane engine development
A 1925 technical report on light aeroplane engine development, issued through the NASA Technical Reports Server and aimed at engineers and aviation designers. The single picture is a Fig. 1 line drawing of an engine block seen in two views, with dashed outlines of internal parts and centre lines marking the axes. For a designer it offers a clean schematic of early aero-engine layout, useful for mechanical diagram or technical drawing references.
