The "Avro Trainer" airplane (British) : a training biplane
A 1930 NACA aircraft circular issued by NASA Technical Reports Server describing the British Avro Trainer, a training biplane, for aeronautical engineers and students of aircraft construction. The pictures are black-and-white technical line drawings of fittings, struts, and fuselage joints, plus a three-view general arrangement with dimensions and a table of wing, aileron, and rudder areas, giving designers a clean model for diagrammatic mechanical drawing.
