From Wikipedia, the free encyclopedia
The Polikarpov I-1 (or sometimes the IL-400) was the first home-produced Soviet monoplane fighter.
[edit] Development
The I-1 (I = Istrebitel or fighter) was a single-seat cantilever low-wing monoplane fighter of mixed construction, built mainly from wood it had aluminium alloy covering on the tailplane, forward part of the wings and the vertical tail. First flown in 1923 it was sometimes known as the IL-400 due to the nose-mounted 400hp (198kW) Liberty engine. Following a crash during the first flight it was rebuilt with a redesigned tailplane and wing becoming the IL-400B. Another prototype was built which was followed by 30 production aircraft, although nearly all the aircraft differed with minor design changes. The I-1 was prone to unintentional spinning and in June 1927 a pilot saved himself from an out-of-control aircraft to make one of the first recorded parachute escapes in the Soviet Union. The aircraft never entered operational service.
