Antonov An-22

rdfs:comment

The An-22 has the general appearance of an enlarged version of the earlier Antonov An-12 except that it is fitted with a twin tail. This gives the An-22 better engine-out performance, and reduces height restrictions for hangars. Also of note are large anti-flutter masses on the top of each tail. The Antonov An-22 "Antei" (; ) (NATO reporting name "Cock") is a heavy military transport aircraft designed by the Antonov Design Bureau in the Soviet Union. Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first Soviet wide-body aircraft and remains the world's largest turboprop-powered aircraft to date. An-22 first appeared for public outside the Soviet Union at the 1965 Paris Air Show. Since then, the model saw extensive use in major military and humanitarian airlifts of the Soviet Union.

n16:abstract

The An-22 has the general appearance of an enlarged version of the earlier Antonov An-12 except that it is fitted with a twin tail. This gives the An-22 better engine-out performance, and reduces height restrictions for hangars. Also of note are large anti-flutter masses on the top of each tail. Being designed as a strategic airlifter, it has the capability to takeoff from austere, unpaved and short airstrips. This is achieved by four pairs of contra-rotating propellers, similar to those on the Tupolev Tu-114. The engines generate significant thrust, and produce a slipstream over the wings and large double-slotted flaps. The landing gear is ruggedized for rough airstrips, and, in early versions, tire pressures could be adjusted in flight for optimum landing performance, although that feature was removed in later models. The An-22 follows traditional cargo transport design with a high-mounted wing allowing a cavernous cargo space of 33m in length and a usable volume of 639m³. The forward fuselage is fully pressurized and provides space for 5 to 8 crew and up to 28 passengers, but the cargo space is pressurized to only 3.55 PSI / 0.245 bar allowing for a lighter airframe. A door equipped pressure bulkhead is located at frame 14, separating the cargo attendant's compartment from the main cargo compartment. This allows the rear cargo doors to be opened during flight for paratroops and equipment drop. Like the An-12, the aircraft has a circular fuselage section. The An-22 has set a number of payload and payload-to-height world records. Only one production variant was built, the standard An-22. Prototypes, such as the one first featured at the 1965 Paris Air Show had fully-glazed noses that lacked the nose mounted radar of production models. Those aircraft had the radar mounted below the right wheel well fairing, forward of the wheels. The Antonov An-22 "Antei" (; ) (NATO reporting name "Cock") is a heavy military transport aircraft designed by the Antonov Design Bureau in the Soviet Union. Powered by four turboprop engines each driving a pair of contra-rotating propellers, the design was the first Soviet wide-body aircraft and remains the world's largest turboprop-powered aircraft to date. An-22 first appeared for public outside the Soviet Union at the 1965 Paris Air Show. Since then, the model saw extensive use in major military and humanitarian airlifts of the Soviet Union.
