Design and development

An-24 at Uzhhorod, Ukraine 21 May 2005

First flown in 1959, the An-24 was produced in some 1,000 units of various versions; in 2019 there are 109 still in service worldwide, mostly in the CIS and Africa.[2]

It was designed to replace the veteran piston Ilyushin Il-14 transport on short to medium haul trips, optimised for operating from rough strips and unprepared airports in remote locations.[3] The high-wing layout protects engines and blades from debris, the power-to-weight ratio is higher than that of many comparable aircraft and the machine is rugged, requiring minimal ground support equipment.

Due to its rugged airframe and good performance, the An-24 was adapted to perform many secondary missions such as ice reconnaissance and engine/propeller test-bed, as well as further development to produce the An-26 tactical transport, An-30 photo-mapping/survey aircraft and An-32 tactical transport with more powerful engines. Various projects were envisaged such as a four jet short/medium haul airliner and various iterations of powerplant.

The main production line was at the Kiev-Svyatoshino (now "Aviant") aircraft production plant which built 985, with 180 built at Ulan Ude and a further 197 An-24T tactical transport/freighters at Irkutsk. Production in the USSR was shut down by 1978.

Production continues at China's Xi'an Aircraft Industrial Corporation which makes licensed, reverse-engineered and redesigned aircraft as the Xian Y-7, and its derivatives. Manufacture of the Y-7, in civil form, has now been supplanted by the MA60 derivative with western engines and avionics, to improve performance and economy, and widen the export appeal.

An-24LL (Letyushchaya Laboratoriya – flying laboratory)
The generic suffix LL can be applied to any test-bed, but in the An-24's case seems to refer to a single aircraft equipped for metrology (science of measurement), to be used for checking the airworthiness of production aircraft.[1]
An-24LP (LesoPozharnyy – forest fire fighter)
Three An-24RV aircraft converted into fire bombers/cloud seeders by installing a tank in the cabin, optical smoke and flame detectors, provision for a thermal imager, racks for carrying flare dispensers and the ability to carry firefighters for para-dropping.[1]
An-24LR 'Toros' (Ice Hummock)(Ledovyy Razvedchik – ice reconnaissance)
At least two An-24Bs converted to carry the 'Toros' SLAR (sideways looking airborne radar) either side of the lower fuselage, for ice reconnaissance, guiding icebreakers, convoys and other shipping.[1][note 1]

Four aircraft converted as Nuclear, biological and chemical warfare reconnaissance versions of the An-24B, carrying RR8311-100 air sampling pods low on the forward fuselage and a sensor pod on a pylon on the port fuselage side.[1]
An-24RT (Reaktivnyy [Uskoritel'] Transportnyy – boosted transport)
Similar to the AN-24T, fitted with an auxiliary turbojet engine.[1]
An-24RT (Retranslyator – relay installation)

SAT Airlines' Antonov An-24RV
An-24RV (Reaktivnyy [Uskoritel'] V – boosted V)
Turbojet boosted export version, similar to the An-24V but fitted with a 1,985-lb (8830 N) thrust auxiliary turbojet engine in the starboard nacelle.[1]

An-24T 'Troyanda' (Ukrainian – rose)
From the 1960s the Soviet Union was faced with nuclear submarine threats that were virtually undetectable with the technology available. To assist in the development of advanced optical, chemical, sonic, infra-red and electromagnetic detection systems, several aircraft were built or modified as test-beds. One significant aircraft was the An-24T 'Troyanda' which was built new, for the development of sonobuoy and infra-red detection systems. As well as equipment inside the cabin, sensors could be mounted in large teardrop fairings either side of the lower forward fuselage, and extra equipment could be carried in extended wing centre-section fairings.[1]
An-24TV (Transportnyy V – transport V)
The export cargo version of the An-24T.[1]
An-24USh (Uchebno-Shturmanskiy (samolyot) – Navigator training aircraft)

The Y-7 is a Chinese reverse-engineered version of the An-24/An-26 family.[1]
MA60
Upgraded and Westernised Y-7.

Notes

  1. The An-24 incident at Gambell, Alaska occurred 27 February 1974, when a Soviet Antonov An-24LR "Toros" (CCCP-47195) ice reconnaissance aircraft, low on fuel, carrying three crew members and twelve scientists, landed at Gambell Airport.
