Antonov An-74
The Antonov An-74 (NATO reporting name: Coaler) is a Soviet/Ukrainian transport aircraft developed by Antonov. It is a variant of the An-72. The An-72 and An-74 get their nickname, , from the large engine intake ducts, which resemble the oversized ears of the popular Soviet animated character of the same name. Design and development The An-74 was initially an upgrade of the An-72 test aircraft, intended to be used in the Arctic and Antarctica; and had the designation An-72A "Arctic". The aircraft's main purpose is to deliver cargo, equipment and personnel over short- and medium-range routes in any climatic conditions ranging from and at any latitude, including the North Pole, and high altitudes. It can operate to and from low grade airstrips such as concrete, pebble, ice and snow aerodromes. Produced in tandem with the An-72, the An-74 can be fitted with wheel-ski landing gear, de-icing equipment and a number of other upgrades allowing the aircraft to support operations in Arctic or Antarctic environments. An unusual design feature of the An-74 (as well as An-72) is the use of the Coandă effect to improve STOL performance, utilizing engine exhaust gases blown over the wing's upper surface to boost lift.
