Notes on the Construction and Testing of Model Airplanes
This 1922 technical report from the NASA Technical Reports Server collects notes on building and testing model aeroplanes, with no named author and no stated audience beyond aeronautical research. Its two plates show a strut drag graph from the British Aeronautical Research Committee and photographs of a biplane model on a mount with a fuselage and floats. A designer could take from them the clean, labelled line-graph style of early engineering documentation and the stark, shadowed sepia photography of small aircraft models.
