Antonov An-72, An-74 ASCC codename: Coaler Light Transport |
DESCRIPTION:
The An-72 first appeared in the late 1970s as a replacement for the An-26 transport. Since its introduction, the An-72 has come to fill a number of roles in the Russian military and also become a popular aircraft with several civil operators. Key to the An-72 design are its many advanced features intended to maximize short takeoff and landing (STOL) operations from rough fields. The plane's two turbofan engines, for example, are located above and forward of the high-mounted wing. In addition to minimizing foreign object damage to the engines, this placement allows the high-speed engine exhaust to be blown over the upper surface of the wing. The exhaust passes over double-slotted flaps placed on the inboard wing and is deflected downward by a phenomenon called the Coanda effect. Combined with triple-slotted flaps on the outboard wing, this aerodynamic design generates considerable lift to reduce runway distance. Other high-lift features, including full-span leading edge flaps, allow the An-72 to operate from very short fields. The An-72 also makes use of rugged landing gear with low-pressure tires that permit operations from unprepared fields, snow, or ice. To further improve arctic operations, Antonov developed the An-74 with ski-landing gear, de-icing equipment, and a number of other upgrades allowing the aircraft to support operations in Arctic or Antarctic environments. Another major variant of the design family is the An-72P maritime patrol model fitted with offensive weapons and various surveillance equipment. Military versions of the An-72 and An-74 continue to serve with the Russian Air Force while the An-74 is popular with Aeroflot and other airlines. At least 150 examples of the An-72 and An-74 were completed by 1994 and the type remains in production.
