Albatros Commercial Airplane L 73
This is a 1926 NACA aircraft circular issued by the National Advisory Committee for Aeronautics, a United States government research body, documenting the Albatros L 73 two-engine commercial airplane through photographs of its framework, fuselage and cabin. The pictures show a biplane airframe under construction, its wing and fuselage structure, landing gear and passenger cabin seating, with a strut-stress diagram, useful to a designer studying early aircraft structure and interior layout as a reference for mechanical drawing and technical illustration.
