Antonov An-71

The Antonov An-71 was a Soviet AWACS aircraft intended for use with the Fighter Bomber forces of the Soviet Air Force, developed from the An-72 transport.

Only three prototypes were built before the program was cancelled.

Antonov An-72

The Antonov An-72 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.

AN-72

Antonov An-74

The Antonov An-74 is a Soviet / Ukrainian transport aircraft developed by Antonov.

It is a variant of the An-72.

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.

AN-72

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.

AN-71

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.

AN-71

The first flight was made on 31 August 1977, but it was only in the 1980s that production started.

The power plant used is the Lotarev D-36 turbofan engine.

AN-74

The An-72 bears some resemblance to the unsuccessful Boeing YC-14, a prototype design from the early 1970s which had also used over wing 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.
