Training airplane "Arado SC 1"
This NASA Technical Reports Server item is a 1927 aircraft circular on the Arado SC 1 training airplane, issued for technical readers rather than the general public. Its pictures are black-and-white photographs of the airplane, its landing gear, fuselage frame and engine bed, with a few line drawings, giving a designer hard-edged mechanical forms and tubular steel structure to borrow for industrial or technical imagery.
