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 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.
