The Junkers G 31 was an advanced tri-motor airliner produced in small numbers in Germany in the 1920s. Like other Junkers types it was an all-metal low-wing cantilever monoplane. Compared to modern aircraft only the corrugated duralumin metal skin so typical for Junkers aircraft seems unusual. However in the mid-1920s all-metal construction and an aerodynamically ‘clean’ configuration were remarkable.
