Fluttering of the Tail Surfaces of an Airplane and the Means for Its Prevention
A 1929 NACA technical memorandum on aircraft tail flutter, issued by the National Advisory Committee for Aeronautics for engineers and aviation researchers, and held in the NASA Technical Reports collection. Its page shows photographs and line drawings of biplanes in several views, with figure labels 10, 11 and 12 printed beside them. A designer could take from it the clean technical plate layout, with photographs paired against labelled line diagrams and angled sepia views of aircraft.
