Seventy five years ago this month,
the Soviet Union introduced its first
all-metal airplane, the Tupolev ANT-14. Built
of noncorrosive steel by the Central Aero-Hydro Dynamic Institute for use on
the Moscow-Vladivostok air route, the 36-passenger plane had a wingspan of 134
ft. 6 in. and was 85 ft. 3 in. long.
To help the Tupolev ANT-14
achieve an operational ceiling of 4,220 m, five air-cooled, radial engines
produced 480 hp each. With an empty weight of 10,650 kg and a maximum take-off
weight of 17,146 kg, the all-metal aircraft could fly at a maximum speed of 147
mph, and had a range of 746 miles. Before being grounded in 1941, the ANT-14 carried
over 40,000 passengers and served as the flagship of the Soviet propaganda
squadron.
Although there is some
information about the Tupolev ANT-14 on the World Wide Web, little of it is in
English. Do you know something more about this aircraft? If so, please let us
know by commenting on this story.
