The first aircraft ordered to newborn Antonov KB was special agricultural aircraft designated SKhA-1. The idea of this aircraft was studied by O.K.Antonov since 1940, and choice of biplane scheme was made after serious analysis of different options.
By the State Order the ASh-21 engine had to be used. But designer was sure that more powerful ASh-62IR will be more suitable. As a result, aircraft was tested with two interchangeable powerplants (each with its own propeller).
First flight with ASh-21 was performed on August 31, 1947 (pilot P.N.Volodin). Trials continued until July 1948. It became clear that with the ASh-62IR engine aircraft became really multipurpose - light commuter transport and passenger functions were obvious.
Major material for fuselage - duralumin D-16T. Fixed landing gear - steel. Wing and controls skin - fabrics (on later versions leading edge has metal covering up to main spar). Mechanically actuated differential ailerons, elevators and rudder, using cables and push/pull rods; electric trim tab in port aileron, rudder and port elevator; full-span automatic leading-edge slats on upper wings provide excellent slow speed safety and high lift; electrically actuated slotted trailing-edge flaps on both wings. Dual controls and blind-flight instrumentation are standard.
Passenger door is a part of 1.53x1.46m2 cargo hatch. Fuel tanks (1200l, 900kg) are in the upper wing.
Normal crew is two, but single pilot is allowed to fly An-2 when no passengers embarked. During winter season An-2 operates on skis. An-2 skis are equipped with pneumatically-controlled brakes.
STOL performance of An-2 suppled Soviet (and World) aviation with capable transport aircraft which can operate at fields accessible only for light aircraft (like Yak-12 or Po-2) with 100...200hp engines. In 1948- 1987 An-2 carried more than 370.000.00 passengers and performed more than 96% of agricultural works.
The Antonov An-2 is well known in the World as a first class work-horse. It is not exactly pretty but it is very functional, and arguably the finest bush plane in the world in its price class.
Since 1957 under license production in China as Yunshuji-5 (Transport aircraft 5). General purpose Y-5N and agricultural Y-5B are also in production. Versions An-2T and An-2R were under production in Poland by PZL Mielec since 1960, now drastically reduced.
Over 11,950 (15,000?) An-2s built by Mielec for domestic use and export to USSR/CIS (10,440), Bulgaria, former Czechoslovakia, Egypt, France, former East Germany, Hungary, Iraq, North Korea, Mongolia, Netherlands, Nicaragua, Romania, Sudan, Tunisia, Turkey, the UK, Venezuela and former Yugoslavia; in 1989, AICSA of Colombia assembled two An-2s from kits supplied via Pezetel.
About 300 are still in service with Russian Air Force, mostly for parachute training. Much more - in civil agricultural, forestry and transportation. None airplane before or since has been able to carry as much into strips as short and be as maintainable and utilitarian as the An-2.
