Vojenska-Smolik S.16 airplane : all-metal long-distance observation bi-plane
This is a 1927 NACA aircraft circular, issued by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers, documenting the Vojenska-Smolik S.16 all-metal observation biplane through photographs and drawings of its structure. The pictures show the airframe's welded tubular and truss framing, close-up views of the metal joints, and a three-view orthographic drawing, useful to a designer for technical line work, schematic diagrams, and industrial structural detail.
