Tupolev ANT-14
It has been credited as Russia's first all-metal aircraft, with a corrosion-resistant-steel structure.Powered by five 358 kW (480 hp) Gnome-Rhône Jupiter 9AKX radial engines, it was capable of carrying a crew of three, as well as 36 passengers, at a maximum speed of 236 km/h (147 mph).It had a non-retractable tailwheel undercarriage whose main gear consisted of dual (fore-aft) wheels.[2][3] On 17 March 1933, the Soviet Union set up an aerial propaganda squadron, named after Maxim Gorky, and the ANT-14 was assigned to it as its flagship, being named Pravda (Truth) after the Soviet newspaper and was used mainly for sightseeing flights over Moscow,[4][5] but did carry out occasional tourist flights to Kharkov and Leningrad (now Saint Petersburg), while it visited Bucharest in 1935 to help celebrate a festival being held there at the time.[3][4] Data from Illustrated Encyclopedia of Propeller Airliners,[6] Tupolev aircraft since 1922[7]General characteristics Performance
