Antonov An-72 and An-74

Antonov An-72

The Antonov An-72 (NATO reporting name: Coaler) is a Soviet/Ukrainian transport aircraft, developed by Antonov. It was designed as an STOL transport and intended as a replacement for the Antonov An-26, but variants have found success as commercial freighters.

The An-72 and the related An-74 get their nickname, Cheburashka, from the large engine intake ducts, which resemble the oversized ears of the popular Soviet animated character of the same name.

Design and development

The An-72 first flew in December 1977. Produced in tandem with the An-72, the An-74 variant adds the ability to operate in harsh weather conditions in polar regions, because it can be fitted with wheel-skis landing gear, de-icing equipment and a number of other upgrades, allowing the aircraft to support operations in Arctic or Antarctic environments. Other An-72 versions include the An-72S VIP transport and An-72P maritime patrol aircraft.

An unusual design feature of the An-72 is the use of the Coandă effect to improve STOL performance, utilizing engine exhaust gases blown over the wing's upper surface to boost lift. The first flight was made on 31 August 1977, but it was only in the 1980s that production started. The powerplant used is the Lotarev D-36 turbofan engine. The An-72 bears a resemblance to the Boeing YC-14, a prototype design from the early 1970s (design submitted to the Air Force in February 1972) which had also used overwing engines and the Coandă effect.

The rear fuselage of the aircraft has a hinged loading ramp with a rear fairing that slides backwards and up to clear the opening. Up to 7.5 tons can be airdropped while there are folding side seats for 52 passengers.

Operational history

The An-72 has STOL capabilities: its takeoff roll is 620 metres and its landing run is 420 metres. This aircraft was designed to be used on unprepared surfaces: its robust undercarriage and high-flotation tyres allow operations on sand, grass or other unpaved surfaces.

In January 1997 and 1998, the Paris-Dakar rally was assisted by two An-72 aircraft. In 1999, a total of four aircraft of this type joined the rally.

Variants

  • An-72 "Coaler-A": Preproduction aircraft. Two flying prototypes, one static test airframe and eight preproduction machines.
  • An-72A "Coaler-C": Initial production STOL transport with a longer fuselage and increased wingspan.
  • An-72AT – "Coaler-C": Freight version of the An-72A compatible with standard international shipping containers.
  • An-72S – "Coaler-C": Executive VIP transport fitted with a galley in a front cabin, work and rest areas in a central cabin, and 24 armchairs in a rear cabin, can also be reconfigured for transporting freight or 38 passengers or as an air ambulance carrying eight stretchers.
  • An-72P: Patrol aircraft. Armed with one 23 mm GSh-23L cannon plus bombs and/or rockets.
  • An-74: Arctic/Antarctic support model with room for five crew, increased fuel capacity, larger radar in bulged nose radome, improved navigation equipment, better de-icing equipment, and can be fitted with wheel-skis landing gear.

Civil operators

In August 2006, a total of 51 An-72 and Antonov An-74 aircraft remain in airline service. Major operators include Badr Airlines (three), Air Armenia (three), Enimex (five), Gazpromavia (12), and Shar Ink (eight). Some 17 other airlines operate smaller numbers of the type.

Antonov An-74

Design and development

An-74 was initially the upgrade of the An-72 test aircraft to be used at the Arctic and Antarctica and had the designation An-72A "Arctic". The aircraft's main purpose was to deliver cargo, equipment and personnel over short- and medium-range routes in any climatic conditions ranging from −60°C to +45°C and at any longitudes, including the North Pole, and high altitudes. It can operate to and from low grade airstrips such as concrete, pebble, ice and snow aerodromes.

Produced in tandem with the An-72, the An-74 can be fitted with wheel-skis landing gear, de-icing equipment and a number of other upgrades allowing the aircraft to support operations in Arctic or Antarctic environments.

An unusual design feature of the An-74 (as well as An-72) is the use of the Coandă effect to improve STOL performance, utilizing engine exhaust gases blown over the wing's upper surface to boost lift. The power plant used is the Lotarev D-36 turbofan engine. The An-74 bears a resemblance to the Boeing YC-14, a prototype design from the early 1970s which had also used overwing engines and the Coandă effect.

The rear fuselage of the aircraft has a hinged loading ramp with a rear fairing that slides backwards and up to clear the opening. An-74 has the payload of 7.5 tons, including up to 10 passengers/couriers (up to 52 passengers depending on the variant), operating ceiling of 10,100 meters and cruising speed of 550—700 kph. The aircraft may also be used for highly specialized operations:

  • pilotage and vessel escort.
  • establishing and servicing of drifting stations.
  • research operations in Arctic or Antarctic regions.
  • visual ice patrol.
  • fishery reconnaissance.

Operational history

As of Jan 1, 2006, 23 out of 30 aircraft registered in Russia were in operation.

Variants

  • An-74: Arctic/Antarctic support model with room for five crew, increased fuel capacity, larger radar in bulged nose radome, improved navigation equipment, better de-icing equipment, and can be fitted with wheel-skis landing gear.
  • An-74A: Passenger or freighter model.
  • An-74MP: Marine Patrol version. Can transport 44 soldiers, 22 para-troops, 16 stretchers with medical staff, or 10 tonnes of cargo.
  • An-74T: Freighter version equipped with an internal winch, roller equipment, and cargo mooring points, can also be fitted with static lines for paratroops or dropping air cargo.
  • An-74T-100: Variant of the An-74T fitted with a navigator station.
  • An-74D.
  • An-74-100: Variant of the An-74T fitted with a navigator station.

Notable accidents and incidents

On 16 September 1991, an An-74 carrying a cargo shipment of fish from Petropavlovsk-Kamchatskiy to Kiev via Lensk and Omsk crashed after take-off from Lensk Airport, killing all 13 people on board. The cause of the accident was an overloading of the aircraft, combined with the premature retraction of the wing flaps.

On 23 April 2006, a Libyan Air Force An-74TK-200 carrying food aid to Chad crashed near the village of Kousséri in neighbouring Cameroon after abandoning its landing at N'Djamena. All six Ukrainian crew members were confirmed dead.

On 27 November 2006, an Iranian Revolutionary Guards Corps Antonov An-74, serial number 15-2255, crashed on take-off at Tehran Mehrabad Airport. There were 37 fatalities, out of 38 occupants on board the aircraft.

    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.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. 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).
