Antonov An-22

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. The An-22 first appeared publicly outside the Soviet Union at the 1965 Paris Air Show. Since then, the model has seen extensive use in major military and humanitarian airlifts for the Soviet Union.

Design and development

In the late 1950s, the Soviet Union required a large military transport aircraft to supplement the Antonov An-8 and An-12s then entering service. Originally known as the An-20, the model is a conventional multi-engined high-wing design. In the early 1960s, the Antonov bureau produced a wooden mock up at its Kiev, Ukraine, workshops of what was designated the Model 100. The prototype, now designated the An-22, was rolled out on 18 August 1964 and first flew on 27 February 1965. The prototype was given the name Antheus and, after four-months of test flying, was displayed at the 1965 Paris Air Show. All aircraft were built at the Tashkent State Aircraft Factory and the first military delivery was made to the Air Transport Wing at Ivanovo Airbase in 1969.

The aircraft was designed as a strategic airlifter, designed specifically to expand the Soviet Airborne Troops' capability to land with their then-new BMD-1 armoured vehicles. The An-22 cargo hold can accommodate four BMD-1 compared to only one in the An-12.

It also has the capability to takeoff from austere, unpaved, and short airstrips, allowing airborne troops to perform air-landing operations. 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 large 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 with 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.

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.

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. Antonov designated a variant with a modified electrical system and an additional augmented flight control system the An-22A but the designation was not used by the military.

A proposed civil airliner version capable of seating 724 passengers on upper and lower decks was planned but wasn't constructed. (For comparison, a typical Boeing 747 can carry 400–500 passengers.)

Variants

  • An-22 : Three original were prototypes built at the Antonov facility in Kiev,Ukraine, with glass nose.
  • An-22 : Initial production variant with external start system, 37 built at Tashkent.
  • An-22A : Improved variant with air-start capability, modified electrical system, and updated radio and navigation equipment, 28 built at Tashkent.
  • An-22PZ : Conversion of two An-22s to carry wing centre sections or outer wings of Antonov An-124 or An-225 externally above fuselage. Fitted with third centreline fin.

Several other An-22 variants were projected and constructed by Antonov but never entered serial production, notably a nuclear-powered aircraft and a ballistic missile platform.

Operational history

The An-22 was originally built for the Soviet Air Force and Aeroflot (the state airline). Rearming from An-12 in the Air Force began in July 1974. Several Military Transport Aviation units were equipped. The 12th Mginsk Red Banner Military Transport Aviation Division (based at Migalovo) was one of the units which had its three regiments entirely equipped with the An-22s. Another unit that operated it was the 566th Solnechnogorsk Military Transport Aviation Regiment, which used the An-22 from 1970 to 1987.

An early use of the An-22 was to deliver Soviet humanitarian aid to earthquake-hit Peru in July 1970. One An-22 disappeared on 18 July during these relief flights. An-22s were also used to deliver Soviet military aid to Egypt and Syria during the Yom Kippur War in 1973, to Angola in 1975, and to Ethiopia in 1977.

The An-22s from Migalovo were used for the initial deployment of the Soviet Airborne Troops (VDV) during the 1979 Soviet invasion in Afghanistan. One An-22 was shot down near Kabul on 28 October 1984. In 1980, one An-22 crashed at Vnukovo Airport while two crashed at Migalovo (in 1992 and 1994).

In 1984, military An-22s were used to deliver Mi-8 helicopters to Ethiopia during drought relief operations.

In 1986 the aircraft of the 8th Military Air Transport Aviation Regiment from Migalovo were used to deliver materials for the Chernobyl disaster relief operation.

During 1987 the An-22s were used to deliver military equipment to Angola. A year later the military An-22s were used to deliver 15,000 tons and 1,000 personnel for the 1988 Spitak earthquake relief operation in Armenia.

The An-22 aircraft were often seen at the Le Bourget Air Show, and in 1988 delivered an engine from An-124 to the Farnborough Airshow.

In late 1980s, the An-22s were used to deliver Internal Troops to many regional conflicts during and after the breakup of the Soviet Union. In 1995 they deployed the Russian peacekeeping force from the 98th Guards Airborne Division during the Bosnian War.

Approximately 45 An-22s remained in service by the mid-1990s, mostly with the Russian Air Force, but these are slowly being replaced by the bigger turbofan-powered Antonov An-124. The remaining An-22s appear to be operated by an independent military transport aviation squadron at Migalovo base in Tver.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
