An-22 Antonov
An-22 Antei
ASCC codename: Cock
Heavy Transport

DESCRIPTION:
Until the advent of the C-5 Galaxy, the An-22 Antei (Antheus) was the world's largest aircraft, and the design remains the world's largest turboprop-powered airplane. The An-22 follows traditional cargo transport design with a high-mounted wing allowing a cargo space 108 ft (33 m) in length and with a usable volume of 22,500 cubic ft (639 cubic m). In fact, the An-22 is basically an enlarged version of the earlier An-12 except that the tail was redesigned to incorporate twin vertical tails. The aircraft achieves excellent performance thanks to its four powerful turboprop engines, each employing contra-rotating propellers that generate a significant slipstream over the wings. Combined with large double-slotted flaps along the wing trailing edge, the An-22 is capable of operating from relatively short runways for a plane of its size. The powerful engines have also allowed the An-22 to set a number of payload and payload-to-height world records. The landing gear are ruggedized for operations from rough airstrips, and the tire pressures can be adjusted in flight for optimum landing performance. A pressurized forward fuselage provides space for 5 to 8 crew and up to 28 passengers, but the cargo space is unpressurized allowing the rear cargo doors to be opened during flight for paradrops. Although 100 examples of the An-22 were ordered for the Soviet Air Force and Aeroflot, only about half of these are actually believed to have been built. Approximately 45 remained in service by the mid-1990s, mostly with the Russian Air Force, but these are slowly being replaced by the An-124.
