The Antonov An-2 ("kukuruznik"—corn crop duster; USAF/DoD reporting name Type 22,[5] NATO reporting name Colt[6]) is a Soviet mass-produced single-engine biplane utility/agricultural aircraft designed and manufactured by the Antonov Design Bureau beginning in 1947.[4] Its remarkable durability, high lifting power, and ability to take off and land from poor runways have given it a long service life. The An-2 was produced up to 2001 and remains in service with military and civilian operators around the world.The An-2 was designed as a utility aircraft for use in forestry and agriculture. However, the basic airframe is highly adaptable and numerous variants of the type 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 and lightly armed combat versions for dropping paratroops.[7]The most common version is the An-2T 12-seater passenger aircraft. All versions (other than the An-3 and the An-2-100) are powered by a 750 kW (1,010 hp) nine-cylinder Shvetsov ASh-62 radial engine, which was developed from the Wright R-1820.[4] The An-2 typically consumes 2.5 l/min (0.66 US gal/min; 0.55 imp gal/min).[8]
