1.General description. Specific features

plane technical destiny

The Ilyushin Il-76 transport clearly appears as a military design. Its high wing and strong landing gear give it the ability to operate from airfields with rough or unpaved runways, while its rear loading ramp guarantees easy loading and even air dropping capabilities. On the military side, both an airborne tanker and an early warning version of the Il-76 have been developed.

Nevertheless, the Il-76 can be found in widespread commercial use as a freighter. Comparable in size to the B707 and DC-8, strong demand for medium sized freighters boosted the activities of the Il-76 after the political opening of the former Sovjet Union. Besides CIS airlines carrying both domestic and international freight on Il-76s, the aircraft found also work in Africa, the Far East and Europe. Even British, Swiss and South African airlines are to be found among the carriers operating the Il-76, albeit still under joint-venture agreements with Russian partners.

A stretched version, the Il-76MF equiped with more powerful Perm PS-90 engines, is currently being tested.

The aircraft was first conceived by Ilyushin in 1967 to meet a requirement for a freighter able to carry a payload of 40 tons (88,000 lb) over a range of 5,000 km (2,700 nmi; 3,100 mi) in less than six hours, able to operate from short and unprepared airstrips, and capable of coping with the worst weather conditions likely to be experienced in Siberia and the Soviet Union's Arctic regions. It first flew on March 25, 1971.

Production of Il-76s was placed in Tashkent, Uzbekistan (then a republic of the Soviet Union). Some 860 of basic transport variants were made. In 1990s modernized variants were developed (MF, TF), but were not produced in significant quantity due to financial problems of the major user, the Russian Air Force. The prototype of longer variant Il-76MF, with bigger capacity, first flew on 1 August 1995. The production ceased around 1997, and the factory since deteriorated. Some commercial aircraft were modernized to IL-76TD-90VD, starting from 2004, using new engines PS-90 to meet European noise limits[. In 2005, China ordered in Russia 34 new Il-76MD's and 4 tankers Il-78, and the factory in Tashkent completed 16 incomplete airframes. Production of the IL-76 at a new factory in Ulyanovsk in Russia, in cooperation with Tashkent works, is under consideration.
