Antonov An-2 ネクタイ

A digital rendering of a ski-equipped Soviet Antonov AN-2 (Антонов Ан-2) in flight in Siberia. You may change the background color. In 2017 the Antonov Company, located in the Ukraine, will celebrate the 70th anniversary of the AN-2's maiden flight. The AN-2 (Russian nickname: кукурузник [kukuruznik or “maize farmworker”] referred to by NATO as COLT) is the world’s largest single-engine biplane. Its extraordinary slow-flight capabilities make it supremely suited for short, unimproved fields, and some specialized variants have also been built for cold weather and other extreme environments. It fills the same niche in Russia and parts of East Asia as does the venerable Douglas DC-3/C-47 in the West. Since its first appearance in 1947, the AN-2 has been produced in great numbers; over 5,000 were built in the USSR. Since 1960, most AN-2’s have been built at in Poland, with over 12,000 made before full production ended in 1992. Limited production from part stocks continues. The AN-2 is also built under license in China as the Shijiazhuang Y-5. North Korea operates man AN-2s for use by special forces units. Save for the Lockheed C-130, the AN-2 has been in, more or less, continuous production for longer than any other aircraft. The AN-2 was designed as a utility aircraft for use in government-owned forestry and agriculture. However, the basic airframe is highly adaptable and numerous variants have been developed. These include hopper-equipped versions for crop-dusting, scientific versions for atmospheric sampling, water-bombers for fighting forest-fires, flying ambulances, float-equipped seaplane versions, lightly armed combat versions for dropping paratroopers, and of course the most common AN-2T version, which is the 12-seater passenger aircraft. The AN-2 has no stall speed quoted in the operating handbooks (the stall speed being the speed at which the aircraft is traveling too slowly for the airflow over the wings to keep it aloft). Pilots of the AN-2 say the aircraft can be flown in full control at 30 mph (as a contrast, a modern Cessna 4-seater light aircraft has a stall speed of around 55 mph). This slow stall speed makes it possible for the aircraft to fly backwards (if the aircraft is pointed into a headwind of, say, 35 mph, it will travel backwards at 5 mph whilst under full control). This is a rare ability, even for Short Take Off and Landing (STOL) aircraft. Only the German Fieseler Fi-156 “Stork” of World War II has better slow-speed ability. An interesting note from the pilot’s handbook reads: “If the engine quits in instrument conditions (blind flying when you can’t see the ground) or at night, the pilot should pull the control column full aft (it won’t stall) and keep the wings level. The leading-edge slats will snap out at about 40 mph (64 km/h), and when the airplane slows to a forward speed of about 25 mph [40 km/h], the airplane will sink at about a parachute descent rate until the aircraft hits the ground.”
