Farman F.120
The Farman F.120 and its derivatives were a family of multi-engine airliners and bombers of the 1920s built by the Farman Aviation Works in France.
==Design and development==
The Jabiru, which was named after a Latin American stork, was a fixed-undercarriage sesquiplane powered by either two, three or four engines, depending on the variant. It featured and unusually broad chord, low aspect-ratio main wing and a very deep fuselage. The tri-motor variant had the centerline engine mounted high, giving it an unusual appearance.
The F.121 or F.3X was the first version to fly, with four 180 hp Hispano-Suiza 8Ac V8 engines mounted in tandem push-pull pairs mounted on stub wings, however this caused cooling problems for the rear engines and the F.120/F.4X version followed shortly afterwards, powered by three 300 hp Salmson Az.9 radial engines. Development continued and a single F.122, modified from an F.4X, was powered by two 400 hp Lorraine 12Db engines. Two military versions were also built, the F.123 with two 450 hp Hispano-Suiza 12Hb V12s, or F.124 with two 420 hp Gnome et Rhône 9Ad Jupiter radial engines.
