The Tupolev I-14 ( Russian Туполев И-14 , also: ANT-31 , АНТ-31) was a Soviet fighter aircraft ; it was designed by Pavel Sukhoi , who at the time was working on Andrei Tupolev's design team belonging to ZAGI .
development
The first drafts were made in 1932. The machine was designed as a low wing all-metal construction and was to receive a retractable landing gear.
The prototype made its maiden flight in 1933 . It was still equipped with a rigid ski undercarriage and was powered by a Bristol-Mercury engine. The first production copy flew a year later and received the Soviet M-22 engine, which was later replaced by the more powerful M-25 . The I-14 showed excellent flight characteristics and orders were given to build 55 of this type. Later a further development called I-14bis appeared with a Wright R-1820´-F-3 drive. In the end, however, only 18 aircraft were built in two versions, as the model was much more complicated in comparison to the Polikarpow I-16 , which of course had an impact on the production times and the maintenance effort.
The I-14 was also used for shooting tests with two single-shot large-caliber Kurschewski APK cannons. They were not very successful because the aircraft was not designed for this type of armament. Tupolev therefore developed the two specially designed types I-12 and DIP .
